Answer 2

1 . any variable created outside any func. is a global by default...

2 . any variable declaired in any func. is a local variable...to use it/access it out side the func. or in other functions...u have to make it global..

example:

a=5

def hello() :
print(a)
global b
b=7

print(b) ## outside function; accessing b
