Turtle Graphics LibraryTurtle Library is a python built-in graphical module, belonging to one of the standard libraries, in the Python installation directory of the Lib folder, commonly used functions are the following:
Brush control functions
penup(): Lift up the brush;
pendown(): Fall
turtle ActionTurtle.isvisible () returns whether the current turtle is visibleStamp () Copy the current drawingTurtle.write (s[,font= ("Font-name", Font_size, "Font_type")]) writes the text, S is the text content, the font is the typeface parameter, inside is the font name, the size and the type, respectively, the font is optional, The parameters of the font are also optional2. What needs to be stated(1):

A simple drawing tool, called the Turtle drawing (Turtle graphics), which was introduced in the python2.6 version, is the internal library of Python, which can be used to importimport turtleLet's start by explaining the basics of turtle drawing:1. Canvases (canvas)The canvas

The "Little Turtle" turtle is a popular drawing function library in the Python language, imagine a small turtle, starting at a coordinate system origin with a horizontal axis of x, Y, and (0,0), moving in the plane coordinate system based on the control of a set of function directives, Thus drawing a graph on the path

Everyone has learned the concept of variables in middle school. For example, if we set x = 100, we can release x * 2 = 200.
Try the following Python code:
1 import turtle2 3
Python (under Windows) comes with a very interesting turtle drawing program (turtle), which is the protagonist of this series of courses.In Pycharm, create a new project, and then in the Code Editor, enter1 Import Turtle 2 turtle.shape ("
Using Python'sTurtle (Turtle)Module drawing the first step: let Python introduce the Turtle module, the introduction of the module is to tell Python you want to use it.Import TurtleStep Two: Create the canvas. Call the pen function in turtle.t = Turtle. Pen ()Step three: Mov
In Python, a turtle can not only draw a simple black line, but also use it to draw more complex geometry, use different colors, and even fill the shape with color.
First, starting from the basic square
Introduce the Turtle module and create a pen object :
>>> Import turtle>>> t =

In Python, turtles can not only draw simple black lines, but also draw more complex ry, use different colors, and even fill the shape.1. Start with a basic square

>>> import turtle
We have learned the concept of variables in high school. For example: we make x = 100, then we can launch x*2 = 200Try this Python code below1 Import Turtle 2 3 turtle.shape ("turtle")4 x =5 Turtle.forward (x)6 turtle.left (7) , Turtle.forward (+x)8 9 Turtle.exitonclick ()Run the above
whether filled is True. begin_fill () # If yes, start filling in for x in range (): t. forward (size) if x % 2 = 0: t. left (175) else: t. left (225) if filled = True: t. end_fill ()Mystar Functions
Now we can draw a Golden Star (90% red, 75% green, 0% blue)
>>> t.color(0.9,0.75,0)>>> mystar(120,True)
The effect is as follows:
To draw a silhouette for the stars, change the color to black and draw the stars again without coloring them:
>>> t.color(0,0,0)>>> mystar(120,False)
The effect is a

Question:
Similar to snake games. Ask the coordinates of the end point after the given path (F-forward, L-left, R-right) and after more than two points.
Solution:
Simulate it.

Python libraries are numerous and constantly updated, so the most efficient way to learn these libraries is to read the official Python documentation. At the same time with the help of Google and Baidu.

The method is very simple. Multiplication iteration. Instead of a single iteration, it is based on probability iteration. Each result is drawn on the image with coordinates.
