It depends on how often you're going to catch and how often just flow

Hi,
I'm seeing that Python 3.3.0 is not printing the correct ImportError when it
can't
import a module that is imported from another module. Instead of printing the
name of
the module it can't import, it prints the name of the module that is doing the
faulty
import.
Behold:

Hello,

Lets say this is the function...
def foo(msg):
msg.bar = 123
msg.spam = 'eggs'
How do I create an empty object in C?
In Python I would do something like this...
class Msg(object):

Hi All,
I created the Python-UK Community on google+, so if you are using google+ and
you are interested in Python and you are interested in the UK, I heartily
invite you to join.
My intention is to transfer the ownership to the PyCon UK organization, which I
already have contacted a member of

Your __str__ method is not returning a string. It's returning a

you use print as a statement), strings are bytes. The best thing to do

By the way, it's *much* more helpful to copy and paste the actual

That sum() line is a bit of a mouthful. I would refactor it into

Hi all, do you think this code:
$ more myscript.py
for line in open('data.txt'):
result = sum(int(data) for data in line.split(';'))
print(result)
that sums the elements of the lines of this file:
$ more data.txt
