Looking through Python 3.10 release documentation and this is the statement regarding PY_SSIZE_T_CLEAN

Porting to Python 3.10
The PY_SSIZE_T_CLEAN macro must now be defined to use PyArg_ParseTuple() and Py_BuildValue() formats which use #: es#, et#, s#, u#, y#, z#, U# and Z#. See Parsing arguments and building values and the PEP 353. (Contributed by Victor Stinner in bpo-40943.)
