:mod:`runpy` --- Locating and executing Python modules
======================================================
.. module:: runpy
:synopsis: Locate and run Python modules without importing them first.
.. moduleauthor:: Nick Coghlan <ncoghlan@gmail.com>
.. versionadded:: 2.5
The :mod:`runpy` module is used to locate and run Python modules without
importing them first. Its main use is to implement the :option:`-m` command line
switch that allows scripts to be located using the Python module namespace
rather than the filesystem.
When executed as a script, the module effectively operates as follows::
del sys.argv[0] # Remove the runpy module from the arguments
run_module(sys.argv[0], run_name="__main__", alter_sys=True)
The :mod:`runpy` module provides a single function:
.. function:: run_module(mod_name[, init_globals] [, run_name][, alter_sys])
Execute the code of the specified module and return the resulting module globals
dictionary. The module's code is first located using the standard import
mechanism (refer to PEP 302 for details) and then executed in a fresh module
namespace.
The optional dictionary argument *init_globals* may be used to pre-populate the
globals dictionary before the code is executed. The supplied dictionary will not
be modified. If any of the special global variables below are defined in the
supplied dictionary, those definitions are overridden by the ``run_module``
function.
The special global variables ``__name__``, ``__file__``, ``__loader__`` and
``__builtins__`` are set in the globals dictionary before the module code is
executed.
``__name__`` is set to *run_name* if this optional argument is supplied, and the
*mod_name* argument otherwise.
``__loader__`` is set to the PEP 302 module loader used to retrieve the code for
the module (This loader may be a wrapper around the standard import mechanism).
``__file__`` is set to the name provided by the module loader. If the loader
does not make filename information available, this variable is set to ``None``.
``__builtins__`` is automatically initialised with a reference to the top level
namespace of the :mod:`__builtin__` module.
If the argument *alter_sys* is supplied and evaluates to ``True``, then
``sys.argv[0]`` is updated with the value of ``__file__`` and
``sys.modules[__name__]`` is updated with a temporary module object for the
module being executed. Both ``sys.argv[0]`` and ``sys.modules[__name__]``
are restored to their original values before the function returns.
Note that this manipulation of :mod:`sys` is not thread-safe. Other threads may
see the partially initialised module, as well as the altered list of arguments.
It is recommended that the :mod:`sys` module be left alone when invoking this
function from threaded code.
