I would like to understand why when I'm using the a=(with append) the result is none. why the var list is none.
a = ['a','b','b']
b = 'y'
a = a.append(b)
print (a) ---result none

How can someone be asking *why* something occurs when it is clear from the question that she doesn't realize *that* it occurs? – Scott Hunter Jan 18 '20 at 16:08

just delete `a = `. – Jortega Jan 18 '20 at 16:11

1_the question is why it happens in python._ I'm not sure that really addresses the comment by @ScottHunter though. – AMC Jan 18 '20 at 16:53

append returns None.
If you didn't do the assignment, a would have the 'y' appended to it.
