Tbf python guidelines encourage it over if/else in cases like this. "Easier to ask for forgiveness than for permission" or something along the lines
Do you have a specific PEP you're referencing or is this one of those "I assume this must be the case because of how common using try/except statements for flow control are" kind of things?
Pretty sure its not a PEP, but the python glossary mentions it. Searching 'python EAFP' brings up a lot of discussion on the topic too, so if nothing else its definitely a widespread phenomenon
I think there's a difference between "python guidelines encourage" something and "this is a common coding pattern." Yes, you can use try/except for flow control, but there's a lot of people, myself included, who try to use that style sparingly.
