Showing errors explicitly in try... except

[Harlin Seritt]

When using try... except... errors don't show up. Is there a way to
force stderr despite using try...except?

thanks,

If you're looking for stack traces, look at the inspect and
traceback modules. They contain the tools to do just
about anything you need for error reporting. Also there
is a logger module somewhere so you can put the stuff
somewhere permanent if you want.

"force", no. The "stderr" stuff is done by an "unhandled
exception" handler that is at the very top level, so
if you catch the exception, it will never see it to
print it.

Doing this will probably suffice, however:

import traceback
try:
1/0

# one should avoid non-specific exception catching
# in most cases, but this is an example:
except:
traceback.print_exc()
