17aug12 Found this pitifully underdeveloped lesson starting with the Fibonacci sequence. The idea is that the current class has to start somewhere.

There is a more complete Fibonacci lesson elsewhere which is nicely journalled. If you want to start from here right now then do this =====================journal================================== westkill-3:fibonacci gfrancis$ python Python 2.7 (r27:82508, Jul 3 2010, 20:17:05) [GCC 4.0.1 (Apple Inc. build 5493)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> from fibo import * >>> fib(1,1) 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 6765 10946 17711 >>>
