Here is an exercise from Learning Python that I wrote myself:
import sys
import traceback
class MyError: pass
def oops():
raise MyError()
def safe(func, *args):
try:
apply(func, args)
except:
traceback.print_exc()
print 'Got', sys.exc_type, sys.exc_value
safe(oops)
And here is the output:
Traceback (most recent call last):
File "C:/Python24/oops.py", line 11, in safe
apply(func, args)
File "C:/Python24/oops.py", line 7, in oops
raise MyError()
MyError: <__main__.MyError instance at 0x00B475A8>
Got Queue.Empty
Why does it show Queue.Empty as the values for sys.exc_type and
sys.exc_value? I guess I can somewhat understand Empty, because the
instance is basically nothing. But why does it say Queue instead of
MyError? The sample in the book shows "Got hello world", because hello
is the error name and world is the extra data. But mine doesn't seem to
work that way. (They are also using a string exception in the book,
instead of a class.)
Thanks.
