Python Global variable

[chandan kumar]

Hi all,

Please see the below code,in which i'm verifying the global value in python..

CHK=10

def test1():
print "Value of CHK in test1",CHK

def test2():
CHK=40
print "Value of CHK in test2",CHK
test1()

def test3():
global CHK
test2()

test3()

When i ran above code ,I'm getting vlaue of CHK as 40 in test2 method and 10 in test1 method
Can somone explain me why the value of CHK is different in method test1 and test2.

Best Regards,
Chandan
