should not use any character more than twice (alphanumeric, symbol, whitespace...anything)
should not use any external resources
should not use any user input
should not output anything else

An example of a valid python program:

print("He%so world!"%(2*'l'))

Answer*

If this is an answer to a challenge…

…Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.
…Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one. Explanations of your answer make it more interesting to read and are very much encouraged.
…Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.

More generally…

…Please make sure to answer the question and provide sufficient detail.
…Avoid asking for help, clarification or responding to other answers (use comments instead).

\$\begingroup\$ @Josh This is one of the rare events where I miss the downvote button on comments. If we throw away rules there is nothing left to justify the contest at all. \$\endgroup\$
