Python does not know what a CSV file is. It doesn't know what a JPEG is. If you want to work with these things you have to tell Python what they are. If you want to use a library to do that you need to know how to install a library such that Python knows what it is and where it is. You can play around in Photoshop because and get decent results because it already knows what a JPEG is. All of the tools are built around working with 2D images and share a set of abstractions. You might do a shitty job but you're not likely to break your image or be unable to do anything. Python is not "Photoshop for CSV files". It's not Photoshop for anything. So you must learn some basics to use it an Aella decided learning was stupid and she could just copy and paste her way through the process. A rational person confronts by terms they didn't understand in some instructions would take a step back and realize maybe they were missing some fundamentals.
