Fun with primality testing

[François Pinard]

Hi, people.

For your mere enjoyment!  Here is Python code which prints primes below 1000.
At the local Perl mongers meeting, someone showed this nicety to me.


import re
for n in range(2, 1000):
    if not re.match('(11+)\\1+$', '1'*n):
        print n
