I'm currently interning and I've been assigned to work on a project that was left unfinished by a previous intern. The code is quite complicated, with five different pipelines and one main script, and as a beginner in Python, I'm feeling really lost. Every time I look at the code, I get overwhelmed. Any suggestions on how to approach this and make sense of it all would be greatly appreciated!

Take it one step at a time! Run the main code to see what each pipeline outputs. Using simple print statements to log output can help you trace data flow, and once you understand that, making modifications will be much easier.
You should definitely start by reading through the code. It might seem daunting at first, but just take your time and try to understand what's happening in each part. Don't hesitate to ask questions along the way!
Try asking your team what the code currently does and what the goals are for your modifications. If any design documentation exists, that would be super helpful. If not, you might suggest creating some to clarify the next steps. It sounds like the prior intern didn't leave things very organized!
Lock in and really focus. Read the code, check the documentation for the libraries used, and maybe even use tools like AI helpers to get insights about the code flow. Don't just trust what they say; verify it! The best way to get your head around it is to start with the initial code and follow the flow of execution. It might feel like grunt work, but it's the only way to truly grasp it. Don't be afraid to run the pipelines and modify things—it’s a great learning experience, just make sure you're in a safe environment!
Consider using AI tools to help you understand each file's purpose and how they work together. If you grasp the system’s structure well enough, these tools can even assist you in writing new code. This is a huge opportunity to shine and show what you can do!
Break the project down into smaller, manageable tasks. Create a list or outline of what you need to do and write some pseudo code. This will help you organize your thoughts and approach the code step-by-step.

Thanks for the advice! I'll start reading through it more carefully.
