I need some help with this piece of code!
debt -= payment
debt -= interest
It is telling me that -= is not valid.

Read the error message the interpreter is giving you closely. The clue you need is in there.
debt = 5,000 # wrong
debt = 5000 # right
a la python shell you are creating a tuple and then trying to += (concatenate) an int to it
Traceback (most recent call last):
File "", line 1, in
TypeError: can only concatenate tuple (not "int") to tuple
as rsmith said above, get rid of the ','

Don't forget that you never increase the value of month, your loop is endeless, never separate the numbers, only if they are floats. Remember also that, the interest are part of your payment, should be better if it looks like this: debt = debt - (payment+interest), that'll help if they ask you things like, total amount you paid.
