    # interpreted as an integer. If o can be converted to a Python int
    # or long but the attempt to convert to a Py_ssize_t value would
    # raise an OverflowError, then the exc argument is the type of
    # exception that will be raised (usually IndexError or
    # OverflowError). If exc is NULL, then the exception is cleared
    # and the value is clipped to PY_SSIZE_T_MIN for a negative
    # integer or PY_SSIZE_T_MAX for a positive integer.
