Is there any easy way to transfer 4 bit integer on socket?
I want to send like this:
a=5
send_integer(socket_s,a)
and receive like this:
a=receive_integer(socket_s)
Sending and receiving is in binary form, not transfer it to string.
Is there any easy way to do this?

Weren't tuples added when lists already existed?

OK, I'll go with the enthought installation. This seems to be the
path of least resistance. For those of you who have been in my
position, is there a reason NOT to go with the enthought installation
and do things piecemeal instead?

If you have objects that point to the dictionary (something like a cache)
then you want to clear the existing dictionary instead of just assigning
it to empty. If nothing points to it, as

When used as dictionary keys (also everywhere else where they must
be in a constant order).
Yes, this *is* used in practice.

It seems that everywhere a tuple is used one could just as easily use
a list instead.

AFAIK, there is no XML Schema support in PyRXP.
This is really bad enough.
GPL is not an option for us, and a commercial
licence is less good than e.g. MIT or LGP

Clearly, this won't have the same resul
What is the benefit of clearing a dictionary, when you can just reassign
it as empty? Similarly, suppose I generate a new dictionary b, and need
to have it accessible from a. What is the best method, under which
circumstances?

I really tried. I give up.
I got this one last time (for which I'm very grateful).

months = dict([(month,ii) for ii,month in enumerate(calendar.month_abbr)][1:])
Now I want something that's going to give me a string whose value is the

Even more crazy version:

Hi,
I am writing a GUI front end in Python using Tkinter. I have
developed the GUI in a grid and specified the size of the window. The
widgets are centered into the middle of the window. I would like them
to fill the window. I tried using the sticky=E+W+N+S option on the
widgets themselves and
