It was literally a clean class. I only used C language and then briefly looked at the basics of Python and had no problem googling and using it, but things I had never seen in C language suddenly popped out, and as I went into magic methods, intermediate and advanced grammar, and utilization, I felt that Python was really not easy, so I took the class. I paid for Levels 2, 3, and 4 at once, so I will go listen to Levels 3 and 4. Thank you. C language is really explicit, so I had no problem just looking at the code, but Python has a lot of things hidden inside. I thought that if I had any questions in the future, I would be able to find out by printing them out like this by doing the work of printing the ids in detail and checking them with dir. I listened well.
