SIMD powered Python

Hi! Is there any ID ongoing about using SIMD [1] instructions, like SSE [2], to speed up Python, especially regarding functional features, like list comprehension, map and reduce, etc.. ? Best regards, Hugo Ferreira -- [1] http://en.wikipedia.org/wiki/SIMD [2] http://en.wikipedia.org/wiki

Python Dijkstra Shortest Path

(maybe map? list comprehension? some python trick?)... Profiling blames the heapq (eheh). On a my CoreDuo T2300, it takes 1.6seconds to find a path of 800 vertexes in an half a million mesh. Greetings! Hugo Ferreira -- http://mail.python.org/mailman/listinfo/python-list

Drawing Text on a Path

someone give me an hand here? Thanks in advance! Hugo Ferreira -- http://mail.python.org/mailman/listinfo/python-list

Synchronous shutil.copyfile()

-time, it throws an exception. Is there anyway to force a sync copy of the file (make python wait for the completion)? Thanks in advance! Hugo Ferreira -- http://mail.python.org/mailman/listinfo/python-list

re.sub and empty groups

not getting the essence of groups and non-grouping groups. Someone care to explain (and, give the correct solution :)) ? Thanks in advance, Hugo Ferreira -- GPG Fingerprint: B0D7 1249 447D F5BB 22C5 5B9B 078C 2615 504B 7B85 -- http://mail.python.org/mailman/listinfo/python-list

Best memory analyzer?

Hi! I'm using the BGL bindings, but I think I'm having a giant memory leak. Thing is, I'm not sure if it is the bound C++ variables that are not being trashed, or if the leak is inside my program. What is the best way to debug this? Thanks! Hugo Ferreira -- GPG Fingerprint: B0D7 1249 447D

Best way for inter-process communication in Python

PyParsing and Headaches

! Hugo Ferreira BTW, the following is the complete grammar I'm trying to implement with pyparsing: ## L ::= expr | expr L ## expr ::= term | binary_expr ## binary_expr ::= term binary_op term ## binary_op ::= * | OR | AND ## include_bool ::= + | - ## term ::= ([include_bool] [modifier

of hours, including learning about it's API (minus this little inconvenient) what would have taken me a couple of days with, for example, ANTLR (in fact, I've already put aside ANTLR more than once in the past for a built-from-scratch parser). Cheers, Hugo Ferreira On 11/22/06, Paul McGuire [EMAIL

Rendering Vector Graphics

Hi ppl,I need to render high-quality vector graphics with Python. I was thinking of something like 'cairo', though I need to run under win32 and can't find a pycairo package for it. Suggestions?Thanks, Hugo Ferreira-- GPG Fingerprint: B0D7 1249 447D F5BB 22C55B9B 078C 2615 504B 7B85 -- http

Re: Proposal: [... for ... while cond(x)]

I actually like the proposal...If the argument to remove map, lambda and filter can be that list comprehension is more readable, then why can't this one also use it?Which reminds me this discussion: http://awkly.org/archive/can-python-take-advantage-of-mapreduce/ Cheers!HugoOn 8/6/06, Slawomir

Re: Type signature

Which is expecially true when using IDEs with auto-completion.Using VisualStudio/MonoDevelop and C# I rarely need to look at the documentation because I can quickly see what a method accept and returns. And when I need to pass flags or options, enums are much more neat and encapsulated. With
