Feature or enhancement

Proposal:

Python has an internal_PyImport_GetModuleAttrString(mod_name, attr_name) helper function to import a module and get a module attribute. I propose to make this function public to be able to use it outside Python.

UPDATE: Function renamed toPyImport_ImportModuleAttrString().

The function is convenient to use and is used by the following files in Python:

• Modules/arraymodule.c
• Modules/cjkcodecs/cjkcodecs.h
• Modules/_ctypes/callbacks.c
• Modules/_datetimemodule.c
• Modules/_decimal/_decimal.c
• Modules/_elementtree.c
• Modules/faulthandler.c
• Modules/_lsprof.c
• Modules/_operator.c
• Modules/_pickle.c
• Modules/posixmodule.c
• Modules/selectmodule.c
• Modules/_sqlite/connection.c
• Modules/_sqlite/module.c
• Modules/_sre/sre.c
• Modules/timemodule.c
• Modules/_zoneinfo.c
• Objects/abstract.c
• Objects/fileobject.c
• Objects/memoryobject.c
• Parser/pegen.c
• Parser/tokenizer/file_tokenizer.c
• Python/import.c
• Python/pylifecycle.c
