I want to know why this code is giving me a NONE.
def main():
x = ['a','b','c','d','e']
y = ['v','w','x','y','z']
z1 = x.append(y)
z2 = x.extend(y)
print z1
print z2
main()

3They both return `None`... – DavidG Mar 26 '18 at 15:25

@blue_mango just put x+y instead x.append(y) – HISI Mar 26 '18 at 15:39

@hisi Thanks. But I guess that is a substitution for extend instead of append. I still wonder why the code returns a NONE. – blueMango Mar 26 '18 at 16:05

list.append(x) add an item to the end of the list and return None. – Eduardo Basílio Mar 26 '18 at 16:37
