Python custom traceback?

[Doug]

I'm interested in exploring a custom traceback error handler, but I
can't figure out if it is possible. I'd like to do something like:

#-----------------------------
from mylibrary import *
x = 7 / 0
#-----------------------------

such that I can control what happens when an unhandled exception is
thrown. I want to put something in mylibrary. Now, I know I can:

#-----------------------------
import sys
try:
x = 7 / 0
except:
custom_handler(sys.exc_type, sys.exc_value, sys.exc_traceback)
#-----------------------------

but I don't want to surround all of my code in a try/except clause. Is
this possible? Are there hooks into the standard interpreter's
unhandled exception handling?

Thanks for any hints,

-Doug

I think you might want the traceback module - have you looked at it?

You can take a look at sys.excepthook and see if that does what you
need.

For example:

>>> import sys
>>> def myhook(type, value, traceback):
...     print 'type:', type
...     print 'value:', value
...     print 'traceback:', traceback
...
>>> sys.excepthook = myhook
>>> 1/0
type: <type 'exceptions.ZeroDivisionError'>
value: integer division or modulo by zero
traceback: <traceback object at 0x63fd0>


I hope that helps.

Hi All,

The deadline for submissions of presentation proposals for PyCon 2007 is October 31st. Given how much good came out of getting education meetings at last year's pycon (this list, for starters), I wanted to see if we could do some advanced planning to make this year's pycon even better.

I've got to run (students are coming), so I'll follow this up later...

Definitely count me in for whatever I can do to help out. Of course
we'll want to have the dinner/BOF again, that was very good.

Do we want to suggest an education strand? Well, maybe not quite a
strand, but at least some grouping of ed related talks?

Cheers,
Vern
