[azerty-svg]

Tests about pow(0, 0). According to the documentation it should return 1. Currently there is no checking for this.

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.
