Python draws a beautiful cherry tree (different kinds of cherry + Rose + Christmas tree)

There are many tree diagrams drawn in Python (most of them are turnle libraries), which is very beautiful. I sorted them out and selected some code that I think is good to share with you (I have tested these, and they can be generated indeed)
one cherry tree

  • Dynamic Cherry Blossom generation
    Rendering (this is dynamic):

  •  

  •  

  • Implementation code

  • Many people learn python, master the basic syntax, do not know where to find cases to start.

    Many people who have already done cases do not know how to learn more advanced knowledge.

    Then for these three types of people, I will provide you with a good learning platform, free access to video tutorials, e-books, and the source code of the course!
