Can I optionally include one element in a list without an else statement in python?

Question

I know you can do something like this in python:

>>> conditional = False
>>> x = [1 if conditional else 2, 3, 4]
[ 2, 3, 4 ]

Answer 1

You can do it with a slice

x = [1, 3, 4][not conditional:]

eg

>>> conditional = False
>>> [1, 3, 4][not conditional:]
[3, 4]
>>> conditional = True
>>> [1, 3, 4][not conditional:]
[1, 3, 4]
