eldoc-documentation-function is defined in eldoc.el as:

    (defvar eldoc-documentation-function #'ignore
      ...)

and eldoc.el is preloaded, so the var should not be nil.

Which version of Emacs is that?  Your report seems to say Emacs-24.4,
but the add-function call in python.el is new in master, AFAICT.
Are you by any chance using the python.el from master with an
older Emacs?
