Like Aahz said, getattr(x, i) is your ticket. However, keep in mind that the
behavior of dir() is not guaranteed across current and future versions of
Python. You may have better luck using x.__dict__.keys() - or in Python 2.3,
you can get away with this:

for i in x.__dict__: print getattr(x, i)

Since dictionaries are their own key-iterators now.
