I have found in my own work life that the problems you get from large python code is quite different from a large C code. The python code usually start out very good and readable but as it get extended and changed it tend to create a massive mess that is hard to navigate. The C code in comparison don't generally get extended or changed at all since the initial work to even add the simplest change tend to require a large initial dive into the design, custom types and design details, that such code tend to mostly be left alone.

The upside with the python code is that a complete rewrite of parts that has get extended beyond recognition tend to be easier than expected.
