python_version_tuple in identify_filenames.py returning incorrectly

[h-ssh]

import platform
if platform.python_version_tuple() < ('3','2','0'):
     raise RuntimeError('This script now requires Python 3.2 or above')

python_version_tuple returns a string tuple of the python version - e.g. ('3','10','12')

String comparison in python will return incorrectly in this case

Python 3.10.12 (main, Nov  6 2024, 20:22:13) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> print((platform.python_version_tuple()) < ('3','2','0'))
True

Proposed change

import sys
if sys.version_info < (3,2):
    raise RuntimeError('This script now requires Python 3.2 or above')
