Function print_exception

Lib/traceback.py:128–143

Print exception up to 'limit' stack trace entries from 'tb' to 'file'. This differs from print_tb() in the following ways: (1) if traceback is not None, it prints a header "Traceback (most recent call last):"; (2) it prints the exception type and value after the stack trace; (3) if

(exc, /, value=_sentinel, tb=_sentinel, limit=None, \
                    file=None, chain=True, **kwargs)

def print_exception(exc, /, value=_sentinel, tb=_sentinel, limit=None, \
                    file=None, chain=True, **kwargs):

    occurred with a caret on the next line indicating the approximate
    position of the error.
