Instagram actually has a program for stubbing existing code called MonkeyType. It requires running your code to collect the data, and then after your run finishes you can then apply the new inferred types to your program.

so like can i throw my entire django app at this thing and have it spit out types for me? probably not right?

That's actually correct - it will spit out types it can infer. https://github.com/Instagram/MonkeyType
