Running pydoc [ pydoc <modulename> ] on a python module using Tkinter 
displayed the window defined in the module - not what I was 
expecting..   Running pydoc on

from os import remove
sFile='tmp.tmp'
remove(sFile)

will remove the file tmp.tmp, if it exists. 
If this behaviour is intentional ( as it appears to be, see 
imp.load_module ) & presumably integral to the operation of pydoc, then 
it might be worth providing a warning on the web page ( 
http://docs.python.org/library/pydoc.html ) ?? 
Running a code with default arguments in an arbitrary directory could 
potentially produce unwanted side effects, at the very least..

That's why you shouldn't put code with side effects at the root of a
module, but inside a "if __name__ == '__main__'" guard.

Anyway, it may be worth documenting it!
