What it's saying is you can't add a float and string. If you

OK, The problem is that you cannot change the contents of a

Sorry, I meant the data structures. You mentioned you had a list of
tuples?

You can do:
letterlist[x] += amount
letterlist[x] -= amount

Try it.
I want to be able to add and subtract from a number
in a tuple in a list. Is this the correct syntax?
letterlist[x] = letterlist[x] + amount # for
addition
letterlist[x] = letterlist[x] - amount # for
subtraction
If this is not correct, what is the correct
syntax?
Thanks,

Hello:
This question is regarding the first exercise of the
book "How to think Like a Computer Scientist:
Learning with Python", by Downey, Elkner, and Meyers,
Chapter 13, page 137.
The goal is to write a function printTime that takes a
Time object as an argument and prints it in the form
