A simple idiom is
if __name__ == '__main__':
# tests here
That way the scripts are run when the module is run by itself, but not when
it is imported.
Also, __debug__ is usually 1, but 0 when the -O (optimize) command line
switch is used. -O also removes assert commands. -O -O discards doc strings
as well. So you could put your tests under
if __debug__:
# tests here
And use your production code with the -O command line option.
