> - Dont Count on autocompletion (at least not in eclipse)

Tbh, PyDev for Eclipse is pretty darn good. Doesn't fail me on autocompletion, function arguments etc, except for places where objects are created dynamically. Also, I find it very handy being able to navigate to any one places in my $PYTHONPATH with one keystroke on F3 and get the documentation + the implementation to read through. Keeps me away from most documentation sites and inside the IDE.
