The loop variable that changed

Time: 0:00

What it should do

make_multipliers() returns a list of 3 functions multiplying by 0, 1, and 2. test_multipliers() calls each with 10 and returns the results.

What goes wrong

test_multipliers() returns [20, 20, 20] instead of [0, 10, 20].

Hints

This is a scope and closure bugs bug

Every callback reports the last value, a counter never increments, UnboundLocalError on a variable you can see.
