Hi everyone,

I’m new to working with Python and Pandas at my job, and I’ve started seeing the SettingWithCopyWarning while cleaning data. The confusing part is that my code still runs, so I’m not sure whether this is something I can ignore or if it’s actually causing problems.

I’ve read a few explanations online, but I’m still struggling to understand what this warning really means. Is it telling me that I’m modifying a copy instead of the original DataFrame? If so, what’s the recommended way to avoid this warning and make sure my changes are applied correctly?

I’d appreciate a beginner-friendly explanation, especially if someone can explain why this warning exists and the best practices for handling it in real projects.
