/*
Deprecated function which does nothing.

In Python 3.6 and older, this function created the GIL if it didn’t exist.

Changed in version 3.9: The function now does nothing.

Changed in version 3.7: This function is now called by Py_Initialize(), so you don’t have to call it yourself anymore.

Changed in version 3.2: This function cannot be called before Py_Initialize() anymore.

Deprecated since version 3.9, will be removed in version 3.11.

/*
    Returns a non-zero value if PyEval_InitThreads() has been called. This function can be called without holding the GIL, and therefore can be used to avoid calls to the locking API when running single-threaded.

    Changed in version 3.7: The GIL is now initialized by Py_Initialize().

    Deprecated since version 3.9, will be removed in version 3.11.
