Hey everyone! I've got this Python script that's about 2,000 to 3,000 lines long and mostly consists of functions and methods. Some of these functions are over 100 lines, and honestly, it's becoming quite difficult to read and maintain. I'm really eager to refactor it, but I'm unsure of the best approach to take. My initial thought was to break down the longer methods into smaller helper functions, but I'm concerned that it might still seem cluttered—just with more functions in the same file. Any tips on effective ways to refactor this code?

The first rule of refactoring is: do it for a good reason. Length alone isn’t enough justification. If your code is becoming hard to maintain and read, that's a case for refactoring. Focus on understanding the code first, then only refactor if necessary when you’re making significant changes.
A great way to start is by refactoring your script into modules, creating individual `.py` files for different aspects of your program, and keeping a `main.py` for running everything. This separation can help maintain clarity and organization.
I think you're missing the point. The OP mentioned their code is already tough to read and maintain, so they should definitely consider refactoring.
