There are many "templating" utilities in Python: Yaptu from Alex Martelli,
and Cheetah sprint to mind as two of the simpler packages not too-closely
focused on any one application.

Use a templating utility to perform the replacements you need, then run the
code with "exec".

Ane bear in mind that you have to guard against malicious users in such
schemes, to make sure the code you are running does not perform some
subversive act such as deleting files, sending mail, etc.
