>>> def even(X): ... if X % 2 == 0 : return True ... else: return False ... >>> filter(even, [0,1,2,3,4,5,6]) [0,2,4,6] How to get that output, help please...

Answer 1

filter doesn't return a list anymore in Python 3.x, so you have to use list().

def even(X):
if X % 2 == 0:
return True
else:
return False
print(list(filter(even, [0,1,2,3,4,5,6])))

You can also use:
print([X for X in [0,1,2,3,4,5,6] if X % 2 == 0])

Answer 2

Then what you typed should work. I hope you aren't typing the command prompt (>>>)?

Answer 3

I am using python 2.7x
