Hi @ezio-melotti I've added the description using https://github.com/python/cpython/labels as the reference. Please check.

@za, FYI, if you include the phrase "Closes #821" or "Fixes #821" in your PR description, then issue #821 will be automatically closed when this PR is merged. That will mean that you won't have to ping a maintainer to manually close an issue after the PR has been merged :)

Hi @AlexWaygood Thanks! I've updated the PR description :-)

[ezio-melotti]

I'm going to close this since the name of labels don't match anymore and there are conflicts. The list of labels is already being updated in another PR. Thanks anyway for the PR!
