How to learn to apply OOP and SOLID in your code. /u/TheOushen Python Education

Hi, I am a beginner Python developer. I plan to work in the backend direction. I learned Python syntax, several frameworks, understood the essence of OOP and SOLID principles, but I ran into a problem that I do not understand how to apply them correctly in practice. Example: having tried to write a simple program (in Tkinter, sqlite3) for registration and authorization, I basically succeeded, but this code looks more like a mess of different functions and strings. Please tell me where I can find material on the principles of writing beautiful code.
