Is it an idea to include a new __filename__ predefined attribute to
2.5, so that __file__ contains the entire path to the module, and
__filename__ only the name of the module?
For instance it's useful to include a not-static reference to the
filename in a scripts usage() section and it's cumbersom
I Steve,
I know it's several ways to isolate the filename. I just want to avoid
the overhead of importing sys or os to achieve it.
Currently I have this in my scripts:

your problem, not mine.

you may experience speed-ups by using
from itertools import izip
and just use izip() instead to avoid the module namespace lookup. The
same applies for the list.append() methods. If you're appending some
million times
a_list = []
a_list_append = a_list.append
