At present, setting the PYTHONPATH environment variable is the only method for defining additional Python module search directories.

This PEP introduces the ‘-P’ valued option to the python command as an alternative to PYTHONPATH.

On Unix:

will be equivalent to:

env PYTHONPATH=$SOMEVALUE python

On Windows 2K:

will (almost) be equivalent to:

set __PYTHONPATH=%PYTHONPATH% && set PYTHONPATH=%SOMEVALUE%\
   && python && set PYTHONPATH=%__PYTHONPATH%

This option is equivalent to the ‘java -classpath’ option.

This option is intended to ease and make more robust the use of Python in test or build scripts, for instance.

A patch implementing this is available from SourceForge:
