1. Prelude:When drawing with turtle, you need to install the corresponding Python interpreter and IDE, I installed Pycharm, after installing Pycharm, in Pycharm install the corresponding library module, drawing can introduce turtle module, You can introduce NumPy modules if you want to perform operations.Note: Turtle i
This article mainly introduces the use of Numpy+matplotlib drawing of the basic operation, the article introduced in very detailed, for everyone to learn matplotlib drawing has a certain reference learning value, the need for friends below to learn together.
Briefly
Matplotlib is a python-based 2D drawing
This article mainly introduces the method that Python uses Pylab library to realize the line-drawing function, and analyzes the operation skill of Python using the correlation function of Pylab library to realize the function of drawing

on the hexagonal grid.Back to the original high-dimensional feature space, the songs are clustered into a user-defined number of groups (k=10 can do a good job of visualizing them). For each group, find the song that is closest to the group center.On the hexagon grid, use different colors to color the song in the K Group Center.Insert different colors on the XY screen, depending on the distance from the other songs to each group center.
