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?

>>> print 'hello world'
hello world

This only shows the output:

> system("python -c 'print \"hello world\"'")
hello world


BTW, I asked in r-help but have not got a response yet (if I do, I'll post the answer here).
