nope. the import statement does this, but the Python interpreter doesn't (running test.py as a script isn't the same thing as importing it as a module). the inter- preter does recognize a compiled file, though: $ cat >q.py print "hello" $ python2.4 q.py hello $ ls q.pyc ls: q.pyc: No such file or directory $ python2.4 -c "import q" hello $ ls q.pyc q.pyc $ python2.4 q.pyc hello however, this only works if you're passing in a filename: $ python2.4 <q.py hello $ python2.4 <q.pyc sys:1: DeprecationWarning: Non-ASCII character '\xf2' in file <stdin> on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details File "<stdin>", line 1 m= ^ SyntaxError: invalid syntax and it usually won't work if you use another Python version: $ python2.3 q.pyc RuntimeError: Bad magic number in .pyc file </F> -- http://mail.python.org/mailman/listinfo/python-list
