Terry J. Reedy <[email protected]> added the comment:
Printing an exception is defined as printing the exception message, which
currently is e.args[0]. We will not change that as it would break code
worldwide. To print more, the class name can be used directly or as a key into
a dict of replacements or replacement functions.
Questions and vague ideas should be directed to python-list. Fleshed out ideas
can go to python-ideas.
