How to port Python 2 Code to Python 3

Python 2 reached its official end-of-life at the start of 2020. This means that no new bug reports, fixes, or changes will be made to Python 2 - it's no longer supported: see PEP 373 and status of Python versions.

If you are looking to port an extension module instead of pure Python code, please see Penyesuaian Porting Modul Ekstensi ke Python 3.

The archived python-porting mailing list may contain some useful guidance.

Since Python 3.11 the original porting guide was discontinued. You can find the old guide in the archive.
