As JG said, number is your variable (much like i in your C code). A for loop in python is really like a foreach loop in C# (I think Visual C++ has it too). Basically, it iterates over a container. So you can use that syntax with lists too:

fib = [0,1,1,2,3,5,8]
for number in fib:
    print number

A range object acts sort of like a container, containing all the numbers between a and b.
