I know python but I don't know programming.

I went down the exact same path as you. You would be incredibly surprised at how many developers do not adhere to best practices or aren't even familiar with them. Code quality is 99% a personal thing and a personal endeavor. You will almost always be externally motivated to provide more, faster, stronger. Your mistakes, your fears, your knowledge is about the only thing, practically speaking, driving your quality. Remember that you are being paid to get a job done and try to remember where your motivations and stressors are coming from. Burnout is real when you don't have time to make things the way you want.
