With Python's turtle module you can draw a lot of beautiful graphics, the following is a brief introduction to how to use.The tool that needs to be used has Python,python installation here is no longer elaborate.

First, importImport Mode one:
From Turtle Import *
If you import this way, you can use all of the methods of the library directly in the file.For example: (Set a 300*300, brush in 100*100 position, draw a circle)
From turtle Import *

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 is not supported in Pycharm, it may be a probl
Explanation of the output table (export table) of the small turtle PE (PE description 09)
When the PE file is executed, the Windows loader loads the file into the memory and loads the dynamic link library (usually in DLL format) file registered in the import table into the address space, then, modify the IAT of the executed File Based on the function export information in the DLL file.

I wrote an article two months ago.
Article: "My little turtle is about to change the shell." unexpectedly, there were so many friends who clicked (currently reading 614 million) and left a message. Most of my friends are the same as me, I love turtles, but I am not very professional with them. I have read more than 80 messages, which is of great help to me, especially with peace of mind. I have provided many very professional and valuable comments to
Prior to this, we have done some practice and understanding of this input table, which will help you to further deepen the understanding of this concept.

Turtle: Drawing ModuleThe object of the drawing can be understood as a turtle or a robot or a pen, and it can only understand limited commands. the origin of the drawing window (0,0) is in the middle of the canvas, and the default orientation is horizontal to the right.
