If you are on Linux and more interested in the result than the
programming exercise, I would suggest the following non-Python solution:
find . -type -f -exec sed -i 's/foo/bar/g' {} \;
Having said that, I would be interested to know what the most compact
way of doing the same thing in Python might be.
