Teach you how to use Python to draw Doraemon A dream jingle cat step by step, and familiarize yourself with the basic drawing operation of Python step by step.
Analysis: Dingdang cat consists of head, face, eyes, eyes, nose, mouth, beard, necklace, bell, body, bib, arms, hands and feet. Among them: head, face, eyes, eyes, nose, mouth and beard constitute one part; The rest of the components constitute one component. Don't talk nonsense, put on the code.
I hope you will pay attention to it and praise it, which is also our support.
