Fibonnaci.py
#This program calulates the fibonnaci sequence a = 0 b = 1 count = 0 max_count = 20 while count < max_count: count = count + 1 #we need to keep track of a since we change it old_a = a a = b b = old_a + b #Notice that the , at the end of a print statement keeps it # from switching to a new line print old_a, print
Output:
0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181
