Hi, guys! I need some help in Problem Set 1b. Everything works fine but...why do we need to set a user input variable 'initialBalance' equal to 'balance' ? My code didn't run correctly for quite a while since I didn't differentiate between the user input balance value and a variable named 'balance. They both had the same name.
Here is what I had:
balance = float(raw_input('Enter your balance:'))
.....
......
balance = balance

If you change the ballance as you go, you may still need the intial for something else.
