Commit d30a1ad0443 translated the symbol file checker from perl to
python by doing a literal translation in most cases. Unfortunately one
string formatting operation was not really translated into python
leaving users with non-helpful error:

'Symbol $1 is listed twice'

Not a deal breaker, but IMO should at least the "new" syntax for string
formatting using the .format() method (works both with python 2 and 3).

Ideally, we'd move to python 3.6+ (since 2 will die in about 2 months) and
started using string interpolation (or f-strings if you want).

Well, looks like we are not using that anywhere. And frankly, f-strings are horrible. This is the most readable style for us, C developers IMO.
