I can't import some python libraries (PIL, psycopg2) that I just installed with MacPorts. I looked through these forums, and tried to adjust my PATH variable in $HOME/.bash_profile in order to fix this but it did not work.
I added the location of PIL and psycopg2 to PATH.
I know that Terminal is…

I want to pass a chunk of Python code to Python in R with something like system('python ...'), and I'm wondering if there is an easy way to emulate the python console in this case. For example, suppose the code is "print 'hello world'", how can I get the output like this in R?

Hi,
I am currently struggling to call a non python program from a python script.
I have a ~1000 files that when passed through this C++ program will generate ~1000 outputs. Each output file must have a distinct name.
The command I wish to run is of the form:
program_name -input -output -o1 -o2…

Basically you code in a stricter version…

My problem: I've found that processing large data sets with raw C++ using the STL map and vector can often be considerably faster (and with lower memory footprint) than using Cython.
I figure that part of this speed penalty is due to using Python lists and dicts, and that there might be some tricks…

I just came across Cython, while I was looking out for ways to optimize Python code. I read various posts on stackoverflow, the python wiki and read the article "General Rules for Optimization".
Cython is something which grasps my interest the most; instead of writing C-code for yourself, you can…

I'd like to make a Python package containing some Cython code. I've got the the Cython code working nicely. However, now I want to know how best to package it.
For most people who just want to install the package, I'd like to include the .c file that Cython creates, and arrange for setup.py to compile…

I was trying to speed up some code, and then I tried compiling a class and a function using cython
and WOW! I havn't measured it yet but it looks at least 10x faster.
I first looked at cython just two days ago, I'm very impressed!
However, I can't get eval() to work.
