Multiple statements in list compherensions in Python?

Question

Is it possible to have something like:

list1 = ...

currentValue = 0
list2 = [currentValue += i, i for i in list1]

I tried that but didn\'t wor

Answer 1

For your edited example:

currentValue += sum(list1)

or:

for x in list1:
    currentValue += x

List comprehensions are great, I love them, but there's nothing wrong with the humble for loop and you shouldn't be afraid to use it :-)

EDIT: "But what if I wanna increment different than the collected values?"

Well, what do you want to increment by? You have the entire power of python at your command!

Increment by x-squared?

for x in list1:
    currentValue += x**2

Increment by some function of x and its position in the list?

for i, x in enumerate(list1):
    currentValue += i*x
