Basically its just a collection of data.
You can get a

The generic term for a collection of N items is a tuple.

Your problem is that you say:

You then try to use amount in main, but main has no amount in it.
Either move "amount=0" inside main, or put a global reference:

Where do you intend the variable cash_in to come from?
The system doesn't know what cash_in is beyond that you mentioned it and that
makes it impossible to multiply it with dollar which is a float type.
If cash_in is supposed to be an input from the user, you probably should make
it an int typ

If you're going to put a function inside your class (since you're using self in
