Issue warning if no "return" in function?

[Poster28]

What would you suggest to check python programs for non-syntax error.
One example I could think of that one might forget to "return" a value from
a function.

How could I check for these and maybe other mistakes?

Check out PyLint (http://www.logilab.org/857) or PyChecker (http://
pychecker.sourceforge.net/).

I really recommend getting into the habit of writing tests for all of
your programs. I like the test-driven approach; write a test that
reflects the behaviour you want and -then- write your code. If it
doesn't succeed, there's most likely something wrong with your code.
