I think this is easily seen by a for loop:
for something in range(20):
print something
In the above something is a variable, in this case an int(which is
immutable). However, something is changed every time it goes through the
loop.
It's the equivalent of:
x = 0
x = 1
x = 2

Then you can do:

Everything (all keys) start at 0, so you can do += with no problem.
