With this framing, you could probably set the default for --style to ["default"] and then append "pep257" if len(self.namespace.styles) <= 1

[DanielNoord]

Yeah I thought about that. However, if users did --style=pep257 default would be missing so they would need to do --style=pep257,default, which doesn't seem right.
Adding default to style would also work, but this if check accomplishes the same and might be clearer? I don't know honestly 😄

[DWesl]

Depends on how the parser treats default values with action="append". I'd have to look into that to be sure.

[DanielNoord]

Yeah it just appends to the default. So you could end up with ["default", "pep257", "default"]. That's not necessarily any issue I guess.

Since we're treating it as a set, not really. If that bothers you, we could change the action to change the value to a set or frozenset when it's done parsing the command line.
