(3.12+) tokenize exception type is wrong #105390
Description
Bug report
the document exception type for the tokenize.* functions is TokenError -- however it appears it now raises SyntaxError: https://docs.python.org/3.12/library/tokenize.html#tokenize.TokenError
Raised when either a docstring or expression that may be split over several lines is not completed anywhere in the file, for example:
