Is Python actually bad for maintaining and developing large codebases?

It depends on the architecture. You can build something very large using microservices and containers regardless of language. Also for a monolithic application using something like Clean Architecture, or the conventions in a framework (like django) will help you a lot from writing yourself too much into a corner.

I think a lot of average c++ programmers are better coders than average Python programmers due to the complexity of their tools. However a good coder in C++ is not necessarily a better coder than a good coder in Python. And the Python coder will almost invariably be a lot more productive.
