Apparently it's so hard on the Internet to search for the answer to query "convert woff to ttf python". But an important nugget of information is available on a random github issue, where anthrotype said:

Or via python code, you can

from fontTools import ttLib

font = ttLib.TTFont("MyFont.woff")
font.flavor = None  # was "woff"; `None` restores the default value, for

non-compressed OpenType font.save("MyFont.ttf")

Use system package python3-fonttools. This is for a woff version 1 (not woff2) file specifically, but this library supports multiple filetypes so it will probably do woff2 just fine.
