The editor consulted all kinds of materials and sorted out a simple and easy-to-use method of operation. I hope it will be helpful to answer the question of "how to draw a bar chart with python". Next, please follow the editor to study!

In the process of setting up, some data are displayed in tables, so it is difficult to see the differences between the data and highlight the characteristics of the data, so I want to make a bar chart, which is specially recorded here and ready for later use.
