I have built Python-3.13.11 from source and ran the test test_urllib2net in Linux ubuntu 6.8.0-53-generic. The test seems to fail because of typo in accessing fp from a HTTPResponse object. I have created a PR for the same

https://github.com/python/cpython/pull/143506

If this is a valid issue please merge the same.

CPython versions tested on:

3.13

Comienza con Lib/test/test_urllib2net.py, especialmente con TimeoutTest.test_ftp_basic, test_ftp_default_timeout, test_ftp_no_timeout y test_ftp_timeout. Ejecuta test_urllib2net para reproducir los cuatro errores y compara el acceso fallido a HTTPResponse con el PR vinculado gh-143506. La tarea estará terminada cuando estas pruebas pasen en Python 3.13.
