Hi,
I was looking through some of our source code and I found this:
initModule( "$Revision: 3.1 $".split(" ")[1] )
In this example, it looks like only the '3.1' is actually passed to the
function. Which leads me to speculate that the rest of it is just there to
make it easier for the developer when looking at source code to see what
version of the module is being used.
The only thing I think i notice is its also passing a list of one element?
Is this a typical way to do this in python?
Thanks
David

It looks like that it may be for the benefit of CVS; manually updated
version numbers are a pain.

One element of a list; that's not quite the same thing.

Revision control systems such as CVS and Subversion know how to
find and update information such as the revision tag when it is
formatted in that manner (leading/trailing $ etc). The programmer
also apparently thought it would be a good idea to use the revision
number programmaticall y, which explains the surrounding split()
and indexing operations, and the function call.

To amplify David Brodie's answer:
The string "$Revision: 3.1 $" is probably supplied by
CVS, the Concurrent Versioning System, and that literal in
that line of the program changes every time the Python
module is checked into change control. You're really
looking at a slick way to communicate between CVS and the
module user.

For what it's worth, I wrote the original PEP 318. I probably wasn't
qualified, but I just wanted a nice simple way to declare class methods
without having to repeat the function name. After submitting it to BDFL

python-dev increased rapidly. It was evident that I was in over my head,
so I asked more someone more experienced to take over.

Consider this macro

Of course, this can't be safely used as in

Python is supposed to be readable, but after programming in Python for
a while I find my Python programs can be more obfuscated than their C/C
++ counterparts sometimes. Part of the reason is that with
heterogeneous lists/tuples at hand, I tend to stuff many things into
the list and *assume* a structure of the list or tuple, instead of
declaring them explicitly as one will do with C structs. So, what used

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.
