So I spoke with the dev for Anaconda-mode and it seems that it doesn't work in 
the inferior python mode buffer, which is why it's not even listed as a minor 
mode in my inferior buffer. Disabling Anaconda-mode as you suggested doesn't 
change any of the described behavior, which isn't too surprising. 

C-M-i provides all the correct completion options. The issue seems to be with 
whatever mechanism is behind generating the autocomplete tooltips. I'm not 
entirely sure what I changed, or if this never worked to begin with and I was 
mistaken in the first place, but if I do the following, for example: 

sys.p M-x company-complete to manually start completion I get "No completion 
found". But if I type C-M-i I get a completions buffer with the appropriate 
methods. 

Oddly, if I type sys.p and then change my focus to another application (e.g. I 
click inside of firefox) and then switch my focus back to Emacs, typing "a" 
(for example) results in the autocompletion tooltip to pop up. 

There seems to be something funky going on, but I'm not entirely sure where to 
direct my questions.
