Drawing with the Turtle module in python

Introduction: Turtle is a simple drawing tool. It provides a turtle that you can interpret as a robot, only to understand the limited instructions.

1. Write the following line in the header of the file, which allows us to insert Chinese in the statement

#-*-Coding:utf-8-*-

2. Import Turtle Library with import turtle

3. The origin of the drawing window (0,0) is in the middle. By default, turtles move to the right.

4. There are many commands for manipulating turtle drawings, which can be divided into two types: one for motion commands and one for brush control commands

(1) Motion command:

Forward (d)	Move forward distance d to represent distance
Backward (d)	Move Backward distance D represents distance
Right (degree)	How many degrees to the right?
Left (degree)	How many degrees left to rotate
Goto (X,y)	Move the brush to a position of coordinates (X,Y)
Stamp ()	Draw the current graphic
Speed (speed)	Speed range [0,10] integer drawn by the brush

(2) Brush control command:

Down ()	Draw the drawing when the brush falls and moves
Up ()	The brush is lifted and the graphic is not drawn when moved
Setheading (degree)	Turtle headed, degree, representing angle.
Reset ()	Restore all settings
Pensize (width)	The width of the brush
PenColor (colorstring)	Color of brushes
FillColor (colorstring)	Draw the fill color of a graphic
Fill (ture)
Fill (False)
Circle (radius, extent)	Draw a circle, where radius is radius, extent is a degree, for example, if extent is 180, draw a semicircle; to draw a circle, you don't have to write the second argument

5. Several examples

1 draw a triangle with a side length of 60

#-*-Coding:utf-8-*-

Importturtle

A=60

Turtle.forward (a)

Turtle.left (120)

Turtle.forward (a)

Turtle.left (120)

Turtle.forward (a)

Turtle.left (120)

2 draw a square with a side length of 60 and fill it with red, with a blue border

#-*-Coding:utf-8-*-

Importturtle

Turtle.reset ()

A= 60

Turtle.fillcolor ("Red")

Turtle.pencolor ("Blue")

Turtle.pensize (10)

Turtle.fill (True)

Turtle.left (90)

Turtle.forward (a)

Turtle.left (90)

Turtle.forward (a)

Turtle.left (90)

Turtle.forward (a)

Turtle.left (90)

Turtle.forward (a)

Turtle.fill (False)

6. Practice:

1) Draw a Pentagon

2) Draw a hexagonal

3 any input a positive integer m (>=3), draw a polygon (M edge)

4 Draw a pentagram, as shown below, note that the fill is red

5 Draw a Chinese chess board, as shown in the following picture, where the Chinese characters do not have to display:

6 Draw the Olympic five-ring map, of which five colors are blue, black, red, yellow and green respectively. Note Adjust the size and position of the circle according to the actual effect.
