what is happening is once select check box its
variable is not getting set. below is the code. what
could be the problem? i am using python 2.0

=============
from Tkinter import *

def TestCases():

print 'hi'
if(name3.var.get() == 1):
print 'TEST CASE A'
def hostTC():
if(name1.var.get() == 1):
print 'TESTSCENARIO A'
top = Tk()
y1 = IntVar()
name3 = Checkbutton(top, text = "TEST CASE A",
variable = y1, onvalue=1, offvalue=0)
name3.grid()
y2 = IntVar()
name4 = Checkbutton(top, text="TEST CASE B",
variable = y2, onvalue=1, offvalue=0)
name4.grid()
name3.var = y1
name4.var = y2
b1 = Button(top,
text='OK!',command=TestCases())
name3.pack()
name4.pack()
b1.pack()
Tkinter.mainloop()

def main():
global root,name1,name2,name3
root = Tk()
x1 = IntVar()
name1 = Checkbutton(root, text = "Pizza", variable
= x1, onvalue=1, offvalue=0)
name1.grid()
x2 = IntVar()
name2 = Checkbutton(root, text="Salad", variable =
x2, onvalue=1, offvalue=0)
name2.grid()
name1.var = x1
name2.var = x2
b = Button(root, text='OK!',command=hostTC())
name1.pack()
name2.pack()
b.pack()
Tkinter.mainloop()
if __name__ == '__main__':

I do not fully understand what you're are trying to achieve with your code,
but this observation might help you anyway:

[...] b1 = Button(top,
text='OK!',command=TestCases()) [...] b = Button(root, text='OK!',command=hostTC())

[...]

In both cases you do the eqivalent of

b = Button(..., command=None)

as both TestCases() and hostTC() do not explicitly return a value.
You probably want the buttons to invoke TestCases() or hostTC(), and you
therefore must omit the trailing (), e. g.:

b = Button(root, text='OK!',command=hostTC)
