Copyright © 2014 Dr. James D. Palmer; This work is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Iterating on Ranges In the simplest case, we can use for and range to repeat a block of code a fixed number of times:

Copyright © 2014 Dr. James D. Palmer; This work is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Iterating on Ranges Using the start, stop and step parameters the range function can generate many linear sequences: These sequences can count down as well as up:

Iterating on Ranges We can also create more complicated sequences by using the range values to parameterize a more complicated calculation. This loop calculates n factorial:
