Storing the input from a Text Field in Tkinter

I want to invoke the method delImg when the button delete is called. I used the following code segment for it. But the method parameters are highlighted as wrong. I used Tkinter.How to correct it ?

import Tkinter
import sys
from Tkinter import *
from tkFileDialog   import askopenfilename
root= Tk()

enText =StringVar()

#root.geometry("400*400+500+300")
root.title("Welcome")


def Hello():
 mtext = enText.get()
 mlabel2 = Label(root,text=mtext).pack()
 print(mtext)
 return mtext

def callback():
 name= askopenfilename()
 print name
 return name

def delImg(m1,n1):
 if(m1!=n1):
    print("Error")

text = Entry(root,textvariable =enText).pack()
mbtn = Button(root,text="Enter",command=callback,fg='red').pack()
mbtn = Button(root,text="Ok",command=Hello,fg='red').pack()
mbtn = Button(root,text="Delete", command= lambda:          

delImg(mtext,name),fg='red').pack()


#print(mtext)
root.mainloop()
