Ha, ok - Django is not difficult to maintain, Django is a very powerful, carefully built framework with tons of features that can get you up and running with a production ready website very quickly.

Python is difficult to maintain. Full stop. Why? Anything in Python can do anything to anything else - there are no boundaries which makes it basically impossible to reason about code at scale. You need very strictly enforced code quality standards across your entire codebase and libraries in order to be able to trust anything - otherwise you don't know if some method on a class has been swapped out right underneath your feet, or if some field access is actually calling a function which is accessing a database.

Go is super easy to reason about compared to Python - as long as no one is importing unsafe or reflect (easy to check), you have very solid guarantees as to what can happen at any point.
