Why is this printing 'None' in the output? [duplicate]
Because there are two print statements. First is inside function and second is outside function. When a function doesn't return anything, it implicitly returns None.
Use return statement at end of function to return value.
e.g.:
Return None.
>>> def test1():... print "In function."... >>> a = test1()In function.>>> print aNone>>> >>> print test1()In function.None>>>>>> test1()In function.>>> Use return statement
>>> def test():... return "ACV"... >>> print test()ACV>>> >>> a = test()>>> print aACV>>>
