hi, the following sample (from docs.python.org) is a server that can
actually serve only single client at a time.
In my case I need a simple server that can serve more than one client.
I couldn't find an example on how to do that and be glad to get a
hint.
Thanks in advance

I firstly looked at this module and its __doc__, yet I still need an
'hello world' sample. and couldn't get it straight how can I write my
own hello world sample with SocketServer objects.

The following is a code I am using for a simple tcp echo server.

in my table the field row_id is type of uniqueidentifier.
when try to fetch the data, pymssql somehow, encodes the values in a

for example:

while I can invoke methods of empty string '' right in typing
(''.join(), etc.) I can't do the same with empty list
example:
>>> a = [1,2,3]
>>> b = [].extend(a)
>>> b
>>> b = []
>>> b.extend(a)
>>> b
[1,2,3]
I would not use b = a since I don't want changes on 'b' to apply on
'a'

Hi all,
I would like to thank you all for all the suggestions.
what I did was simply extending the super class data with data from
its child
using the id example, Foo.id = 1 is now = [1] and the FooSon does
self.id.append(2)

Although I am experiencing this problem using a specific domain
library (pjsip). Googling this issue show that it is happening to many
libraries in python on mac.
I was wondering whether anyone solved this or alike in the past and
might share what steps were taken.
Note: this python lib works fine
Trying to follow a technique found at bzr I did the following
added to ~/.ssh/authorized_keys the command="my_parder" parameter
which point to a python script file named 'my_parser' and located in /
usr/local/bin (file was chmoded as 777)
in that script file '/usr/local/bin/my_parser' I got the

What is the reason math.pow yields OverflowError while python itself
can
calculate these large numbers. e.g:
>>> import math
>>> math.pow(100, 154)
1e+308
>>> math.pow(100, 155)
Traceback (most recent call last):
File "", line 1, in
OverflowError: math range error
>>> eval(('100*'* 155)[:-1])
1
> Because math.pow returns a float; 100 ** 155 won't fit in a float.
Sure that is the reason.
May I rephrase, my question:
Why not returning another type as long as we can calculate it?
After all, math module is likely to be used on large numbers as well.

Hi,
The nicest thing I like about py2exe is its library.zip which
encapsulate all the dependencies into one single file.

I changed as instructed:
