Question

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

Answer 1

I'm not quite sure what you're trying to do but it's probably something like

list2 = [(i, i*2, i) for i in list1]
print list2

The statement in the list comprehension has to be a single statement, but you could always make it a function call:

def foo(i):
    print i
    print i * 2
    return i
list2 = [foo(i) for i in list1]
