sort(cmp=func)
I have a list of objects that generate code. Some of them depend on others being listed first, to satisfy dependencies of others. I wrote a cmp function something like this: def dep_cmp(ob1, ob2): if ob1.name in ob2.deps: return -1 else: return 1 I also tried returning 0 when there were no dep... 10 Jul 2008 15:29

TypeError, I know why but not how!?
Im looking into PvsNP: http://www.claymath.org/millennium/P_vs_NP/ so I thought I'd write the program just to get a feel for it. But I run into a problem. Why does it all the sudden return None? I mean I know why the program aborts but I dont understand why the None is generated all the sudden. Hitting recursi... 10 Jul 2008 22:41

Manipulating bitsets in struct
I'm using Python to do some simple network programming, and found the struct module very useful for such things, but is there a way to easily manipulate bitsets such as a 16 bit word being split into 4 parts like 2 bits, 1 bit, 4 bits, and 9 bits? Perhaps something like: struct.pack('!h(2:1:4:9)',2,0,1,100)... 10 Jul 2008 01:01

I am trying to redirect stderr of a process to a temporary file and then read back the contents of the file, all in the same python script.

I'm thinking that I use a tuple or dict to represent the struct but a problem is one of the members of the struct is char **, which is not supported by Py_BuildValue. Is there any idi... 10 Jul 2008 01:01

Terminate a python script from linux shell / bash script
Hello :-) I have a question about Python and Linux shell. I have a python program which is permanently resident in the end-user system. I'm currently producing a RPM package, and it works nicely. The problem is that when I uninstall it, my program keeps running in the background, even if the files are deleted. ... 31 Jul 2008 08:15

Python equivalent of call/cc?
Yesterday, I was hacking around a bit, trying to figure out how to implement the semantics of call/cc in Python. Specifically, I wanted to translate this Scheme code to equivalent Python: #### (define theContinuation #f) (define (test) (let ((i 0)) (call/cc (lambda (k) (set! theContinuation k)... 9 Jul 2008 23:59
