Sorry, I meant the data structures. You mentioned you had a list of
tuples?
And you wanted to perform addition./subtraction on memb

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?
