Hi - this mysterious behavior with shelve is just about to kill me. I
hope someone here can shed some light. First of all, I have this piece
of code which uses shelve to save instances of some class I define. It
works perfectly on an old machine (PII-400) running Python 2.2.1 under
RedHat Linux 8.0. When I try to run it under Python for windows ME on a
P-4 1.4 GHz, however, it keeps crashing on reading from the shelved file

Last week I encountered an AttributeError in my unit tests that I
wasn'table to catch with an "except AttributeError" statement.
The problem stemmed from a class that raised an error inside
__init__and defined a __del__ method to clean up resources. I then
discovered asimilar problem in the shelve module. This led me to two
importantdiscoveries:
1. Attributes defined in __init__ after an error is raised will not be

Hi, I have ran into a problem with py2exe 0.5.0 and shelve in python
2.3.3. The script works fine standalone, but not with py2exe.
Does anyone have a solution of workaround for this? Thanks much.
# Begin of setup.py
from distutils.core import setup

I have read a number of threads relating to problems with shelve, but
I couldn't find one directly related my experience, so I would
appreciate some advice. The closest one ended with a recommendation
to upgrade to Python 2.3, but that, unfortunately, is out of my
control. The system I use runs Python 2.2.2, and whichdb gives
dbhash.
The problem only occurs when serializing class instances; lists don't
seem to be affected. Every time...

I wanted to write the following code:
import shelve
try:
db = shelve.open(file, "r")
except SomeError:
print "Oh no, db not found"
Only, I'm not sure what SomeError should be. I tried error,
anydbm.error, shelve.open.anydb.error, etc. but can't find it. Things

Hi,
I'm not a Win ME fan myself (I'm a Mac user), but I'm here in Thailand
developing software for special-needs kids, and the test PC in my home
office is a Win ME machine (sigh). So when I ported my Python program
today to the PC, it quickly crashed. Everything seems to work except
for shelve. Using the latest version of Python (2.5.1), when I do the
following in IDLE on the Win ME machine here's the result:

Hi there!
I am using the "shelve" module in a script to save information in
between runtime sessions of the program. (its a sort of
data collector, so its important to hold on to anything computed ).
In any case, I shelve into a file "test.txt". I notice that when i try
running the program on a different computer (by either emailing or
transfering the file "test.txt" via USB key), the program is unable to
load the shelve file.
What can...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Here is the code in...
