sys.modules is the one true source.
Return the dictionary used for the module administration (a.k.a.
``sys.modules``). Note that this is a per-interpreter variable.
+.. c:function:: PyObject* PyImport_GetModule(PyObject *name)
+
+ Return the already imported module with the given name. If the
+ module has not been imported yet then returns NULL but does not set
+ an error. Returns NULL and sets an error if the lookup failed.
+
+ .. versionadded:: 3.7
.. c:function:: PyObject* PyImport_GetImporter(PyObject *path)
and module are affected by this change. (Contributed by INADA Naoki and
Eugene Toder in :issue:`29463`.)
+* ``PyInterpreterState`` no longer has a ``modules`` field. Instead use
+ ``sys.modules``.
+
* The *mode* argument of :func:`os.makedirs` no longer affects the file
permission bits of newly-created intermediate-level directories.
To set their file permission bits you can set the umask before invoking
