This allows Python code to play nicely with non-filesystem based PEP 302 importers when locating support scripts as well as when importing modules. � N)� read_code� get_importer� run_module�run_pathc @ s( e Zd ZdZdd� Zdd� Zdd� ZdS ) � _TempModulezCTemporarily replace a module in sys.modules with an empty namespacec C s || _ t�|�| _g | _d S �N)�mod_name�types� ModuleType�module� _saved_module��selfr � r � /usr/lib64/python3.9/runpy.py�__init__ s z_TempModule.__init__c C s@ | j }z| j�tj| � W n ty.

Optional arguments: init_globals -- dictionary used to pre-populate the module’s globals dictionary before the code is executed. run_name -- if not None, this will be used for setting __name__; otherwise, __name__ will be set to mod_name + '__main__' if the named module is a package and to just mod_name otherwise. alter_sys -- if True, 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 are restored to their original values before the function returns. Returns the resulting module globals dictionary.
