How do I set up a function so that it can take an arbitrary number of arguments? For example, I have a bunch of expenses which may grow or shrink depending on the client's circumstance and a function that sums them up... hard coding them is tedious. How might I make this dynamic so that it can handle any amount of expenses?
def tot_expenses(self, e0, e1, e2, e3): pass
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.
