New submission from Aaron Hall :
I've written three (or more) answers on Stack Overflow about how to use the functions in the traceback module, and I code Python all day long.
Embarrassing confession: I just recommended the wrong traceback function in email to fix the incorrect usage of another of these functions after pulling up the docs because. I corrected myself before anyone else could correct me, but I find these docstrings incredibly frustrating and problematic.
May I please give them a little more verbiage about their return values?
e.g.:
def format_tb(tb, limit=None):
"""A shorthand for 'format_list(extract_tb(tb, limit))'."""
return extract_tb(tb, limit=limit).format()
should be:
def format_tb(tb, limit=None):
"""A shorthand for 'format_list(extract_tb(tb, limit))',
which returns a list of strings ready for printing'.
"""
return extract_tb(tb, limit=limit).format()
In fact, perhaps the "shorthand" part is an implementation detail that may not even be correct (it doesn't immediately seem to be) and should be removed.
