I am a physics student and I almost finished my third year (I am in sixth semesters ). So I am trying to learn python. I still did not try to learn classes but other than that I know the other stuff in general. I am solving problems at CodeAbbey (currently 80) and at Project Euler (currently 83 problems in there). I am also reading "Learning Python" to improve my skills and learn more about the syntax classes etc.
Next semester I'll apply some places to do an internship. Also, I want to work as an astrophysicist in the future. And as we all know coding is an important skill in the area. Also I' ll go abroad for graduate school. (At least I 'll try)
In this case, is it important to get a PCEP Certificate to show my skills?
Or is it enough if I open a GitHub page and upload my projects/codes?
