Automatic doc lookup of functions in python-mode

Hi all,

Recently I've been learning the built-in python-mode for my python needs and noticed that there is an automatic popup of function documentation in the minibuffer when my cursor is over the function. I've not made any config changes related to python-mode in my init.el.

How do I disable this feature? I wish to load it on demand with C-c C-f or C-c C-d instead. Thanks in advance!
