Hello!
I'm about to parallelize some algorithm that turned out to be too
slow. Before I start doing it, I'd like to hear some suggestions/hints
from you.
The algorithm essentially works like this: There is a iterator
function "foo" yielding a special kind permutation of [1,n]. The
main progr

Hello,
Yesterday, I was at a programming competition. We programmed on Linux
liveCD's and Python was one of the allowed languages (among C and
Java). I cared just about the algorithmic approach so I used Python.
One of the main rules is, that the code reads its standard input and
dumps the result
Hello!
Many times I was suggested to use xrange and range instead of the
while constructs, and indeed, they are quite more elegant - but, after
calculating the overhead (and losen flexibility) when working with
range/xrange, and while loops, you get to the conclusion that it isn't
really worth usi

Usually, when I make some coding mistake (index out of range - in this
case) I just care to fix the mistake and I usually don't mind to
inspect by how much the index was overflowed. It really seems like a
feature that should be embedded in some Python debugger than a feature
in the interpreter itse
Hello!
I'm relatively new to python but I already noticed that many lines of
python code can be simplified to a oneliner by some clever coder. As
the topics says, I'm trying to split lines like this :
'foo bar- blah/hm.lala' -> [foo, bar, blah, hm, lala]
'foobbbar.. xyz' -> [foo, bbbar, xyz]
`range' is especially useful for iterating over long sequences ;-)
for i in range(0,100) :
OverflowError: range() result has too many items
