if then a more convenient way might be found to naturally remove and

maybe it was not included as one might want to remove the list only
x = [1]
x.remove(1)
as opposed to
x = [1]
x.remove(1)
new_list = x
i was looking for like
x = [1]
x.remove(1).return()
I don't understand what this would return? x? You already have x. Is it
meant to make a copy? x has been mutated, so I don't understand the
benefit of making a copy of the 1-less x. Can you elaborate on the
problem you are trying to solve?

Methods in Python usually do one of two things: 1) mutate the
object and
return None; or 2) leave the object alone and return a new
object. This
helps make it clear which methods mutate and which don't. Since
.remove
mutates the list, it returns None.
