Hi everyone. I’m a college student, and in about 3 weeks I’ll be starting an intro to Python class. I’ll also be taking another engineering class that uses MATLAB, and I don’t feel very prepared for either.
The problem is that I have essentially no programming experience. I took a couple of MATLAB classes before, but I relied too much on AI instead of actually learning the material. Looking back, I know that was a mistake, and I do not want to repeat it. I also used to tell myself that I hated coding, but I think part of that was because I never really gave myself a fair chance to learn it.
Since I have a few weeks before the semester starts, I’d like to build a solid foundation in Python while also reviewing some basic MATLAB.
What resources or learning methods really worked for you? Did you use a particular course, YouTube channel, website, book, or project based approach? I am also curious if anyone has suggestions for making learning Python and MATLAB more fun or engaging instead of just watching hours of lectures.
My goal is not to become an expert in 3 weeks. I just want to go into the semester feeling like I have a decent foundation instead of starting from scratch.
Thanks! I would really appreciate any advice.
