In case anyone ever wanted to know how to run the Fibonacci Sequence in Python, here’s how I did it:

1
2
3
4
5
6
7
8
9
/usr/bin/env python

import sys

f_seq = [ 0, 1 ]
while len(f_seq) <= int(sys.argv[1]):
    f_seq.append(f_seq[-1] + f_seq[-2])

print f_seq

Now, all you have to do is run fibonacci.py 20, and it will give you all the numbers through F20 (starting at zero).

Update: I put this up on Github , and have made a couple changes since I initially wrote it.
