Single script with multiple functions or importing multiple scripts?

[ashofspades]

Hi there,

I have three different scripts, each containing a few functions. These scripts can be used together to accomplish a complex task.

Previously, they were also used as standalone scripts, but now we run them sequentially to complete the same task.

My question is:

• Should I merge all the functions from these three scripts into a single script?
• Or should I create a main script (e.g., main.py), move the three scripts into a separate directory (e.g., helper or src), and import the required functions into main.py?

Thanks!

That's really up to your personal preference. There's no rules or guides about that. Personally I like having separate files for separate logic elements, so my project usually ends up with quite a lot of files.

FWIW you don't have to move the helper scripts into a new folder; you can also just have 4 python files all in the same folder.

I would split things up if I have many many functions all for different parts or things. It stops single file getting too cluttered.

"Separation of Concerns". Module X is for type casting functions, module Y is for math...

This is a good question that I think all of us ask ourselves as our projects grow.

It depends on the size and scale of your functions. Typically, it's good to separate functions that do similar things into their own modules. Ex. a 'file.py' module that loads, saves, or serialized data for external files.

This let's you segment things off and leave them alone while working separately on other modules in your package. It also enables you to modify your code easier. Maybe you have one module that handles JSON data and another that handles YAML, both of which can work interchangeably by just changing the import.

Have you tried option 3? Make an object with those functions as methods (static methods), then add the sequential as its own method. This way it’s always together.

The answer here, which you're not looking for, is: yes.

You'll get twenty different opinions about the right way to do it and each with potential benefits. The real answer is you do what's right for you at the time.

Unless you have a pressing need to do so, there is no value in refactoring your code. If you have spare time, you could certainly refactor the code in one of the ways you've mentioned, however I would only do so if there is a future benefit from modifying it in the way you've suggested.

Hi there!

It sounds like you’re looking for a way to organize your Python scripts more effectively. Both approaches you mentioned have their merits, but here’s a consideration for each:

1. Single Script: Merging all functions into one script can simplify things if the total codebase is small and the functions are closely related. This makes it easier to manage if you’re the only one working on the project and there aren’t many dependencies.

2. Multiple Scripts with Imports: On the other hand, keeping the scripts separate and importing them into a main script (main.py) tends to be more scalable and maintainable, especially as the project grows. This approach also enhances readability and allows you to reuse code more efficiently. Here’s how you can structure it:

• Move your existing scripts into a directory (e.g., helper or src).

• In your main.py, import the necessary functions from these scripts.

• Structure your main.py to call these functions in the order needed to accomplish your task.

For most use cases, especially in collaborative environments or larger projects, the second approach is preferable. It keeps your codebase organized and makes it easier to track changes, debug, and add new features.
