I'm currently working on an issue thats taking me longer than it should (I'm a slow). It's a change to a json structure that impacts multiple files in lines that consist of 5+ method chains that I have to track down in other classes and custom libraries to see what it's doing (Java).

It could have been a single Python file using Pandas to build a DataFrame and this change would have been so much easier. And I'm saying that as someone with at least 10x more Java development than Python development.
