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?

For example:

This works (it prints the correct size of /home/support/Maildir dir):
size = subprocess.Popen(["du -s -b " + maildir], shell=True,

I've got an interactive program called my_own_exe. First, it prints out alive, then you input S\n and then it prints out alive again. Finally you input L\n. It does some processing and exits.
However, when I call it from the following python script, the program seemed to hang after printing out the…

I must be overlooking something terribly obvious. I need to execute a C program, display its output in real time and finally parse its last line, which should be straightforward as the last line printed is always the same.
process = subprocess.Popen(args, shell = True,
