[issue41403] Uncaught AttributeError in unittest.mock._get_target

[Andrei Kulakov]

Andrei Kulakov <andrei.avk at gmail.com> added the comment:

More generally, split()/rsplit() are probably the most common operations done on expected string at the start of a function, i.e. most likely to be triggered on the wrong type passed in. At the same time to many new users split()/rsplit() does not imply anything related to strings, and 'split' sounds too generic to expect explanatory results from google search. (although the first few results do point to the right explanation, and rsplit does seem like something that would return helpful search results).

I wonder if it would be helpful, especially for .split() (and rsplit for consistency), to add to the error msg: "... it's likely that a string object was expected instead of <type> object".
