[issue38351] Modernize email example from %-formatting to f-string

[Fred L. Drake, Jr.]

Fred L. Drake, Jr. <fdrake at gmail.com> added the comment:

Does it make sense to change just one example?

I'm not sure what the long-term stance is on whether %-formatting should be replaced at this point, but shouldn't this be a matter of which string formatting approach we want overall, rather than adjusting only specific examples?
