The purpose is rather irrelevant. The modules could be used for an assortment of tasks.
By conditionals I mean if the name of a module contains a substring, such as "asdf" (i.e. "asdf" in module) or matches a pattern of some sort, for example, all modules which match the regex "module[\d]+\.py", which could be "module5.py" or "module11199.py" or "module345.py". -- http://mail.python.org/mailman/listinfo/python-list
