python - Printing using list comprehension

Question

From my Python console

>>> numbers = [1,2,3]
>>> [print(x) for x in numbers]
1
2
3
[None, None, None]

Why does this print three none's at the end?

Answer 1

You should restructure your loop to send arguments to print():

>>> numbers = [1,2,3]
>>> print(*(x for x in numbers), sep='
')

Note that you don't need the explicit generator. Just unpack the list itself:

>>> numbers = [1,2,3]
>>> print(*numbers, sep='
')
