I like generators a lot.  Here's a fun one:

#------ begin code
from __future__ import generators

def fib():
    "unbounded generator, creates Fibonacci sequence"
    x = 0
    y = 1
    while 1:
        x, y = y, x + y
        yield x

if __name__ == "__main__":
    g = fib()
    for i in range(9):
        print g.next(),

#------ end code

c:\python22>python fib.py
1 1 2 3 5 8 13 21 34
