Python loop with int iterator

Question

I seem to recall there is a built-in way of doing this:

i = 0
for value in values:
    # ...Stuff
    i += 1

but in a neater syntax; something like

for value, i in fn(values):
    # ...Stuff

Is my memory correct; and if so, what is the way of doing this?

Answer 1

for i, value in enumerate(values):
