simple try/except question

Is the behavior below expected?
If so, why is the exception not caught?
Thanks,
Alan Isaac

It works for me, using 2.5.1 and 2.4.3 on Windows XP.
Perhaps you reassigned TypeError?
Python 2.5 says:

pyTypeError
<type 'exceptions.TypeError'>

Earlier versions:
pyTypeError
<class exceptions.TypeError at 0x009B4570>

Sorry to have left out that detail.
Yes, it works for me in Python 2.4,
but not in 2.5.1.

The code I posted was copyied from the interpreter.

False alarm.
Fresh start of interpreter and all is well.
Apologies.
Still tracking.
