Writing Quines

quine.py

#!/usr/bin/env python
# This program prints out its own source code
# ===========================================

import sys

def quine(filename):
    f = open(filename, 'r')
    for line in f.readlines():
        print line.strip('\n')

if __name__ == '__main__':
    quine(sys.argv[0])

quine2.py

#!/usr/bin/env python
# This program prints its own source code
# =======================================

def quine():
    code = [
    '#!/usr/bin/env python',
    '# This program prints its own source code',
    '# =======================================',
    '',
    'def quine():',
    '    code = [',
    '    ]',
    '    for i in range(6):',
    '        print code[i]',
    '    for i in range(len(code)):',
    '        print "    " + chr(39) + code[i] + chr(39) + ","',
    '    for i in range(6, len(code)):',
    '        print code[i]',
    '',
    'quine()',
    ]
    for i in range(6):
        print code[i]
    for i in range(len(code)):
        print "    " + chr(39) + code[i] + chr(39) + ","
    for i in range(6, len(code)):
        print code[i]

quine()

A couple of quines I wrote, just for fun. The first is probably the easiest quine you can write that's not an empty file. The second is a more traditional quine, modeled after the example on Wikipedia.
