The documentation for scipy.interpolate.interp1d is silent on what happens when there are ties in the x argument. My experimenting suggests that it returns the rightmost one when that exact x value is requested and uses the closest one when interpolating:
from scipy.interpolate import interp1d
temp = interp1d([0, 1, 1, 2], [1, 2, 3, 4])

Using a pandas DataFrame to get the count of the 10th most frequent value
I have a DataFrame that contains entries of place_ids such as:
place_id
11111
11111
22222
33333
44444
44444
...
I would like to get the count of the 10th most frequent value.
Here's what I've come up with:
print df.place_id.value_counts().nlargest(10).tail(1).values[0]
This seems like too much work. Is there an easier way to get the count of the 10th most frequent place_id?

Beautifulsoup : Is there a difference between .find() and .select() - python 3.xx
Best
I've a simple question :
when you use Beautiful Soup to scrape a certain part of a website, you can use data.find() / data.findAll() or data.select()
Now the question is. Is there a significant difference between the .find() and the .select() methodes? (e.g. in performance or flexibility, or ...)
or are they just the same?
Kind regards

Is this possible?

Math behind scipy.ndimage.convolve
While I have already found the documentation on scipy.ndimage.convolve function and I "practically know what it does", when I try to calculate the resulting arrays I can't follow the mathematical formula. Let's take for example:
a = np.array([[1, 2, 0, 0],`
[5, 3, 0, 4],
[0, 0, 0, 7],
[9, 3, 0, 0]])
k = np.array([[1,1,1],[1,1,0],[1,0,0]])
from scipy import ndimage
ndimage.convolve(a, k, mode='constant', cval=0.0)
# Why is the result like this ?
array([[11, 10, 7, 4],
[10, 3, 11, 11],
[15, 12, 14, 7],
[12, 3, 7, 0]])
I would appreciate a step by step calculation.
Thanks in advance!
Printing a canvas from Tkinter
I have created a canvas with rectangles and labels only which I would like to print. I have only found how to save the canvas to a postscript file like so:

If necessary I would be happy to just print the whole window if that is easier.
How can I print the canvas?

How can I tell if a jquery ui dialog query has been initialized?
I have the following code to detect if a jquery ui dialog is open:

which works fine but I found a situation where this code get called prior to the dialog being initialized in the first place and this if statement seems to just blow up in this case.
What is the best way to check if a jquery ui dialog has been initialized so I can properly handle this situation.

Creating a likelihood heatmap given many pairs of x and y values of different lengths?
So I have generated a bunch of data curves (like thousands), say temperature with depth. so have say 1000 arrays of depths and 100 corresponding arrays of temperature (n.b. they are not all the same length)
What I want to do is create a heatmap where the color corresponds to how often one of these data curves had that value at that depth. i.e. how many curves pass through that particular bin.
Could anyone offer advice on how to do this?

Download a zip file and extract it in memory using Python3
I would like to download a zip file from internet and extract it.
I would rather use requests. I don't want to write to the disk.
I knew how to do that in Python2 but I am clueless for python3.3. Apparently, zipfile.Zipfile wants a file-like object but I don't know how to get that from what requests returns.
If you know how to do it with urllib.request, I would be curious to see how you do it too.

How to call multiple jquery function from .cs file?
I have 2 JQuery functions which I want to call from PageLoad event. The current implementation is as under
ScriptManager.RegisterStartupScript(this.Page, this.GetType(),
"script", "Function1();", true);
ScriptManager.RegisterStartupScript(this.Page, this.GetType(),
"script", "Function2();", true);
The problem is that, the first function is invoked i.e. Function1 and not Function2.
If I change the order of invocation, then Function2 and not Function1 is called.
How to execute both the functions ?
Thanks in advance.

A ply parser should partly treat comments
I'm trying to produce a ply parser that does not entirely suppress comments.
The typical def t_comment(self, t): r'(/*(.|n)?*/)|(//.)' t.lineno += t.value.count('n')
only counts lines and suppresses the comments. For most of the cases, this is just fine. But at one specific instance I need the comment. Is there a way to parse only this comment at the special place without having to specify all the other places where a comment can occur?
urllib2 file name
If I open a file using urllib2, like so:
remotefile = urllib2.urlopen('http://example.com/somefile.zip')
Is there an easy way to get the file name other then parsing the original URL?
EDIT: changed openfile to urlopen... not sure how that happened.
EDIT2: I ended up using:
filename = url.split('/')[-1].split('#')[0].split('?')[0]
Unless I'm mistaken, this should strip out all potential queries as well.
jquery isotope resize to handle expanded accordion
I'm using jquery isotope for a sortable text listing of federal regulatory activities. We list each update in a docket and the list per docket can become quite long. I've added Bootstrap simple accordion panels to items with more than two updates to make each item panel's height fairly consistent. When I open an accordion panel, the isotope pane doesn't resize to accommodate the expanded accordion.
Any ideas on how to get the isotope panel to resize height to handle the expanded accordions?
Thanks!

Python local variable is changing global variable. Why?
Strange behavior on python. Local variable is changing the global variable.
import numpy as np
xc = np.arange(10)
def func(xc,val=3):
xc /= val
return xc
print xc
c = func(xc)
print xc
I can fix it using .copy() function as:
import numpy as np
xc = np.arange(10)
def func(Xg,val=3):
xc = Xg.copy()
xc /= val
return xc
print xc
c = func(xc)
print xc
There's a better another way to avoid this problem?

Scroll a div while using the scrollwheel over another div
Say I have 2 divs side by side. Both are 400px x 400px, and have overflow set to auto. The content inside is taller than 400px so there are vertical scrollbars.
When the mouse is over the div on the left, and the user uses the mousewheel to scroll, I want the other div to scroll, and vice versa.
So basically when a user is using the mousewheel over a certain area, I want to control the scroll of another area respectively.

Store and retrieve chained jquery effects/objects in variable
I want to dynamically change jquery effects by storing the chained objects in a variable and concatenating to selector later, so that i have the latest required effect when it needs to exec. i store a predifined set of jquery chained effects - fadeOut().end().next().fadeIn() - in the data-effect attr, which can change, so i need to reference back to it via a variable to add the effects to $(contentDiv) selector. So something like; $(selector)effect, won't work.
var effects = document.getElementById('effect').getAtttribute('data-effect');
$(contentsDiv).effects;

How do I attach event bindings to items on a canvas using Tkinter?
If I'm using a canvas to display data and I want the user to be able to click on various items on the canvas in order to get more information or interact with it in some way, what's the best way of going about this?
Searching online I can find information about how to bind events to tags but that seems to be more indirect then what I want. I don't want to group items with tags, but rather have specific function calls when the user clicks specific items on the canvas.

Trying to read a file in a subdirectory through a module I imported from that subdirectory
So I have a program with one main module that is in a folder with two other folders. Each of those two folders has a module in it that I've imported successfully, but each of those modules is supposed to be able to open and read a file from their respective folders, but it is unable to find the file it is supposed to import. I think it is looking in the main directory for the file to open, how would I make each module look in its own folder for the files to open?

Removing personal information from the comments in a word file using python
I want to remove all the personal information from the comments inside a word file.
Removing the Authors name is fine, I did that using the following,
document = Document('sampleFile.docx')
core_properties = document.core_properties
core_properties.author = ""
document.save('new-filename.docx')
But this is not what I need, I want to remove the name of any person who commented inside that word file.
The way we do it manually is by going into Preferences->security->remove personal information from this file on save
delaying a function to execute jquery
I want a button pressed, then the button changes style, and a new function loads, after about 1/2 second of the styling.
$(document).on('click', '.capital_answers', function(){
if(!$('#capital_answers').hasClass('answered')) {
answer = $(this).attr('data-answer');
if(answer==1) {
$(this).addClass('capital_correct');
$('#capital_answers').addClass('answered');
capital_correct()
}
else {
$(this).addClass('capital_wrong');
$('#capital_answers').addClass('answered');
}
delay(500).capital_next();
}
});
So as you can see I am using the delay() method currently, which helps in no way. What options are there in delaying a function in this manner?
Using regex to deal with escape characters in URLs

It picks up "regular" URLs perfectly fine; however some of the URLs look like this:

jquery form change
In jQuery, is there a simple way to test if ANY of a forms elements have changed?

});
how would I test if the form has changed since it was loaded?
whats wrong with this statement(count from 0-9)

if counts == 1:
if firstpickplusfive > 9:
firstpickplusfive = 0
if counts == 5:
print firstpickplusfive
z = int(z) + 1
The code prints the first number, but freezes on printing any others. Why isn't this working?

jQuery validation not using errorPlacement HTML
I have the following jQuery Validation code:
$('form').validate({
errorElementClass: 'input-validation-error',
errorClass: 'field-validation-error',
errorPlacement: function (error, element) {
error.html('<i class="icon-warning"></i> ' + error.text()).insertAfter(element);
}
});
Which should be inserting my custom error message html after each element that errors on my page. However I'm finding the plugin doesn't like this and instead overrides whatever I want to put inside the HTML with just the error message itself and removes the <i class="icon-warning"></i>
How can I stop this?

Compressing And Decompressing into .txt in python
So i want to create a program that asks the user to compress or decompress and if compress it asks for a sentence and compresses the outcome and if decompress it saves the outcome of that in a .txt too. I have this currently.
import pickle

compressopen.lower()
if compressopen == "compress":
sentence = input("Please enter a sentence: ")

elif compressopen == "uncompress":

In what ways would Python be considered a more stable language than Ruby?
I have been using Ruby for a while and I find that because if its metaprogramming capabilities it makes things harder to debug and 3rd party code can potentially cause bugs in what you would think would be unrelated areas of your application.
Is python's metaprogramming much tamer and as a result it is easier to keep things under control? I'm not sure if stable is the right word for it but just less-magical in nature which results in more maintainable and understadable code.
If someone knows both python and ruby maybe they can explain if this is true?

Pandas Groupby TimeGrouper and apply
As per this question. This groupby works when applied to my df for a pd.rolling_mean column as follows:
data['maFast']=data['Last'].groupby(pd.TimeGrouper('d'))
.apply(pd.rolling_mean,center=False,window=10)
How do I apply the same groupby logic to another element of my df which contains pd.rolling_std and pd.rolling_mean:
data['maSlow_std'] = pd.rolling_mean(data['Last'], window=60) +
2* pd.rolling_std(data['Last'], 20, min_periods=20)

Disallow safe mode on launch for Selenium in Python?
I'm trying to launch into a website using a Selenium MWE:
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://seleniumhq.org/')
However, it's not working. The process itself hangs until it times out.
I think that the problem is that instead of just launching normally whenever Selenium triggers Firefox it triggers it in safe mode:
Is there a way to disable that behavior?

Need help using split function
This function adds up the numbers between zero in a string. For example ('25025') becomes 25+25. However, if I have a 0 at start and/or end of the string of the string argument being sent to test_string, it creates a space in the at the start/end of the list and won't compute. What can I add to this function to make it filter out both 0s and blank spaces?
def test_one(test_string):
test = test_string.split("0")
numbers=[int(x) for x in test]
print(sum(numbers))
test_one('2022022022')
test_one('02022020')
test_one('25025')
IOError: [Errno 2] No such file or directory: '0.txt'
I am writing a program to read a set of text files from folder "set" to a list.My code for this is
def get_documents():
path1 = "D:/set/"
texts = []
listing1 = os.listdir(path1)
for file in listing1:
with open(file,'r') as f:
lines = f.read().splitlines()
texts.append(lines)
But this gives me Error as
with open(file,'r') as f:
IOError: [Errno 2] No such file or directory: '0.txt'
There are text files inside D:/set/ namely 0.txt,1.txt,2.txt...
What is the reason for this Error?
Rearrange the columns of a pandas DataFrame so that the column with highest total is first
I have this DataFrame:
df = pd.DataFrame({'c1':[1,2,3,4]
,'c2':[2,4,5,6]
,'c3':[5,7,9,10]
,'c4':[-1,3,1,0]
,'c5':[100,1000,1,2]})
df
c1 c2 c3 c4 c5
0 1 2 5 -1 100
1 2 4 7 3 1000
2 3 5 9 1 1
3 4 6 10 0 2
What I don't know how to do is quickly sort the columns so the column with the highest total c5 comes first, then c3, c2, c1 and c4:
c1 c2 c3 c4 c5
0 1 2 5 -1 100
1 2 4 7 3 1000
2 3 5 9 1 1
3 4 6 10 0 2
So is there a command to produce the following result (without hard-coding the column names)?
df[['c5', 'c3', 'c2', 'c1' , 'c4']]
c5 c3 c2 c1 c4
0 100 5 2 1 -1
1 1000 7 4 2 3
2 1 9 5 3 1
3 2 10 6 4 0
Change user agent used with robotparser in Python
I am using the robotparser from the urlib module in Python to determine if can download webpages. One site I am accessing however returns a 403 error when the robot.txt file is accessed via the default user-agent, but correct response if e.g. downloaded via requests with my user-agent string. (The site also gives a 403 when accessed with the requests packages default user-agent, suggesting they are just blocking common/generic user-agent strings, rather than adding them to the robot.txt file).
Anyway, is it possible to change the user-agent in the rootparser module? Or alternatively, to load in a robot.txt file downloaded seperately?
Aligning Kivy objects using pure Python
I can't seem to figure out alignment using pure Python code. My understanding is that we reference root to get relational alignment. However, I haven't been able to get it to work. This code compiles, runs, and then places the button in the bottom left corner. At the 0,0 coords. What am I missing here?

Different way for php and jquery for better work
I am new here and I learned a lot on w3 schools and similar websites about languages. Now I have few question for you guys. Questions are small so I will ask two in one asking:
For php: What is the best different way for security reasons by getting data by post or get.
$post_id = mysqli_real_escape_string($con, $_POST['id']);
$get_id = mysqli_real_escape_string($con, $_GET['id']);
For jquery: What is best different way for getting info from database without reload or is there anyone.
setInterval(function(){
$('#container').load('file.php')
}, 1000);
CORS: origin is not allowed access [duplicate]
This question already has an answer here:
I got this error when doing an ajax call to an endpoint
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8888' is therefore not allowed access.
but why in POSTMAN I tried with the same params and endpoint there's no problem getting the data?
Why is it giving me the error, "the JSON object must be str, not 'bytes'", and how do I fix it?
I was following a tutorial about how to use JSON objects (link: https://www.youtube.com/watch?v=Y5dU2aGHTZg). When they ran the code, they got no errors, but I did. Is it something to do with different Python versions or something?
from urllib.request import urlopen
import json
def printResults(data):
theJSON = json.loads(data)
print (theJSON)
def main():
urlData ="http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_day.geojson"
webUrl = urlopen(urlData)
print(webUrl.getcode())
if (webUrl.getcode()==200):
data = webUrl.read()
printResults(data)
else:
print ("You failed")

Pandas mean across multiple columns
I have a dataframe which I created using numpy arrays (MnthIdx, Val1, Val2, Val3) as:
import pandas as pd
import numpy as np
dfout3 = pd.DataFrame({'Idx': MnthIdx,
'Col1': Val1,
'Col2': Val2,
'Col3': Val3)})
MeanTable1 = pd.pivot_table(dfout3, index=['Idx'], values=['Val1'], aggfunc=[np.mean])
MeanVal1 = np.asarray(MeanTable1['mean'])
MeanTable2 = pd.pivot_table(dfout3, index=['Idx'], values=['Val2'], aggfunc=[np.mean])
MeanVal2 = np.asarray(MeanTable2['mean'])
MeanTable2 = pd.pivot_table(dfout3, index=['Idx'], values=['Val3'], aggfunc=[np.mean])
MeanVal3 = np.asarray(MeanTable3['mean'])
Is it possible that I can do the above 3 steps in 1 steps only.
Why use jQuery on() instead of click()
Currently with jQuery when I need to do something when a Click occurs I will do it like this...
$(".close-box").click( function() {
MoneyBox.closeBox();
return false;
});
I was looking at some code someone else has on a project and they do it like this...
$(".close-box").live("click", function () {
MoneyBox.closeBox();
return false;
});
Notice it seems to do the same thing as far as I can tell except they are using the live() function which is now Deprecated and jQuery docs say to use on() instead but either way why use live/on() instead of my first example?
Having a model to relate to several different models
I have a simple notification model:
class Notification(models.Model):
user = models.ForeignKey(User)
sender = models.ForeignKey(User)
model = '''What to put here?'''
comment = models.CharField(max_length=200)
created = models.DateTimeField(auto_now=False,auto_now_add=True)
I need the notification to relate to several different models, for example; posts, user follows, etc
Is there anyway in django you can relate to several models instead of creating a notification model for each one?
I want to avoid models like this: PostLikeNotification, UserFollowNotification, etc.
So does django have this functionality? I couldn't find it anywhere in the docs.
pandas dataframe- replace row values
I have a dataframe with four columns (see input dataframe below). I need to check if Meta column has pattern relation (example M_relation) then add number from relation column to the meta column value. How this can be done in pandas?
Input dataframe:
--------------------------------------
Entry1 | Relation | Entry2 | Meta |
--------------------------------------
E11 | R_31 | E21 | M_xxx |
E12 | R_21 | E51 | M_relation |
E33 | R_21 | E51 | M_yyy |
E44 | R_41 | E46 | M_relation |
Output:
--------------------------------------
Entry1 | Relation | Entry2 | Meta |
--------------------------------------
E11 | R_31 | E21 | M_xxx |
E12 | R_21 | E51 | M_relation_21 |
E33 | R_21 | E51 | M_yyy |
E44 | R_41 | E46 | M_relation_41 |
--------------------------------------
reading and doing calculation from .dat file in python
I need to read a .dat file in python which has 12 columns in total and millions of lines of rows. I need to divide column 2,3 and 4 with column 1 for my calculation. So before I load that .dat file, do I need to delete all the other unwanted columns? If not, how do I selectively declare the column and ask python to do the math?
an example of the .dat file would be
time mass x y z - - - - -
1 1 1 1 1 ---------
2 2 2 2 2 ---------
I am new to python , so a little instruction to open , read and calculation would be appreciated.

PyGObject - left-click menu on a status icon
I'm starting to write a small panel applet for Gnome and I'd like the user to be able to left-click on the status icon to see some options and information e.g. similar to sound icon in Gnome 3, where you can set volume via left-click while set preferences via right-click. Right-click code is this:
statusicon.connect("popup-menu", right_button_click)
where right_button_click is the name of the function that gets called on right-click event. The important part is "popup-menu". What would be alternative for setting left-click event?
Pandas: Can pandas groupby filter work on original object?
Starting with this question as base.
Python Pandas: remove entries based on the number of occurrences
data = pandas.DataFrame(
{'pid' : [1,1,1,2,2,3,3,3],
'tag' : [23,45,62,24,45,34,25,62],
})
# pid tag
# 0 1 23
# 1 1 45
# 2 1 62
# 3 2 24
# 4 2 45
# 5 3 34
# 6 3 25
# 7 3 62
g = data.groupby('tag')
g.filter(lambda x: len(x) > 1) # filters out lengths > 1.
# pid tag
# 1 1 45
# 2 1 62
# 4 2 45
# 7 3 62
#This would create a new object g:
g = g.filter(lambda x: len(x) > 1) #where g is now a dataframe.
I was wondering is there a way to filter out 'groups' by deleting
them from original object g. And, would it be faster than creating a new groupby object from filtered groupby.
