There were at least two comments suggesting keeping it to one affix at a time:

But I didn't see any big objections to the rest of the PEP, so I think maybe we keep it restricted for now.
That sounds like a good idea. The issue for me is how the function should behave with a list of affixes if one is a prefix of another, e.g.,removeprefix(('Test', 'Tests')). The empty string case is just one form of that. The behaviour should be defined clearly, and while I imagine "always remove the longest" is the "obvious" sensible choice, I am fairly certain there will be other opinions :-) So deferring the decision for now until we have more experience with the single-affix form seems perfectly reasonable. I'm not even sure that switching to multiple affixes later would need a PEP - it might be fine to add via a simple feature request issue. But that can be a decision for later, too. Paul
