The purpose of the -m option is that you can run a script that is located via the Python import path instead of an explicit file path. The idea is that if '/path/to/somewhere' is in sys.path then: python -m script arg1 arg2 is equivalent to python /path/to/somewhere/script.py arg1 arg2 If Python didn't modify sys.argv then 'script.py' would need to be rewritten to understand that sys.argv would be in a different format when it was invoked using the -m option. I believe that it has previously been proposed to include something like sys.raw_argv, although perhaps for different reasons. Although something that might be more useful to the OP (and that I at one point wanted) would be a function similar to execfile but that would launch a separate process using the same interpreter as the current process.
