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 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?

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…

Should I wrap the dict with a multiprocessing.sharedctypes.synchronized() call? Or is another way…

I haven't ever used multi-threading, and I decided to learn it today. I was reluctant to ever use it before, but when I tried it out it seemed way to easy, which makes me wary.
Are there any gotchas in my code, or is it really that simple?

import multiprocessing
def sleep_then_write(content):

How does one use multiprocessing to tackle embarrassingly parallel problems?
Embarassingly parallel problems typically consist of three basic parts:
Read input data (from a file, database, tcp connection, etc.).
