1. Iteration
1. Definite loops: execute a specific (definite) number of times
2. Indefinite loops: execute until a general condition is false
2. For loops
1. General form: for i in iterator
2. Iterator is either list or something that generates a list
3. Very common form: for i in range(1, 10)
3. range() in detail [for.py]
1. range(10) gives 0 1 2 3 4 5 6 7 8 9
2. range(3, 10) gives 3 4 5 6 7 8 9
3. range(2, 10, 3) gives 2 5 8
4. range(10, 2, -3) gives 10 7 4
4. Program: counting to 10 [toten.py]
5. Program: sum the first 10 squares [sumsq.py]
6. Program: Fibonacci numbers [fib.py]
