Python in a Nutshell

Name

print_exc

Synopsis

print_exc(limit=None, file=sys.stderr)

Call print_exc from an exception handler or a function directly or indirectly called by an exception handler. print_exc outputs to file-like object file the traceback information that Python outputs to stderr for uncaught exceptions. When limit is not None, print_exc outputs only limit traceback nesting levels. For example, when, in an exception handler, you want to cause a diagnostic message just as if the exception propagated, but actually stop the exception from propagating any further (so that your program keeps running, and no further handlers are involved), call traceback.print_exc( ).
