The Python Tutorial is a wonderful thing. . .
Anyway, you can either set up your function to take a proper list, and then
discover that the sum function already exists to add up the contents of a list:
def tot_expenses(self, expenses):
self.total_expenses = sum(expenses)
Or, have the function take a variable number of arguments, and do the same thing:
def tot_expenses(self, *args):
self.total_expenses = sum(args)
Cheers,
Nick.
