CSV and PyEnchant Python Program

I'm attemping to comb through a list of a couple hundred thousand words in a csv file, in order to determine which ones are not english. I know I can utilize PyEnchant to do this, but I'm new to coding in general and could use some help on the details. Here's what I have thus far, I've created a list "L" to print out all of the non-English words so that I can check them myself. import enchant import csv L = [] with open('list.csv') as csvfile: shortcut = csv.reader(csvfile, delimiter=" ", quotechar="|") for row in shortcut: d = enchant.Dict("en_US") if d is false: L.append(d) print L Can someone let me know where I've gone wrong here?
