Python has a library calledturtleThis is part of a standard Python installation. To use it, just type:
from turtle imports * of
imported turtle You can experiment with turtle graphics by entering this command directly into the python interpreter, or better yet, add this line at the top of your program and use the turtle plot command in your program!
insideturtlepackage When you run a program with the turtle command, a special window will open where you will draw.
Turtle code sample for drawing stars
turtle star
Turtle can draw complex shapes using programs that repeat simple actions. Code to draw the stars above.
from turtle import * color('red', 'yellow') begin_fill() while True: forward(200) left(170) if abs(pos()) < 1: break end_fill() 完成() The complete turtle reference!
The following table describes the turtle commands needed to get started.

turtle command
General commands availableturtleindicated below. Click on an assignment for more information.
Every time()
Sets the angle input method to degrees. All subsequent angle entries are assumed to be measured in degrees. This is the default setting.
radian()
Sets the angle input method to radians. All angle entries below are assumed to be radial measurements.
reset()
Reset everything to default and clear the canvas. after callingreset, the canvas will be in exactly the same state as it was when the import command was called: you have a blank canvas with a turtle (black, fill set to unfilled) pointing to the center of the right (heading = 0.0).
clearly()
Erases the entire canvas and redraws the turtle. Do not move the turtle.
tracer (n=none, delay=none)
Enables/disables the turtle animation and sets a delay for updating the drawing.
If a non-negative integer n is given, only every nth regular screen update is performed. Can be used to speed up the drawing of complex graphics. When called with no arguments, the currently stored value of n is returned. The second parameter sets the delay value (see delay()).
By closing the turtle, the turtle disappears and pullsa lot ofhurry. The drawing commands are still executed without the turtle and lines are still drawn when the turtle moves. usageupwardsIndownTurn plotting on and off, or just useset up,set, ofgoA function to move without drawing.
forward (distance)
make the turtle move forwarddistance, draw a line behind the turtle. This line is also drawn when the turtle is knocked out.
backward (distance)
move the turtle backdistance, to draw a line along the path traveled. This line is also drawn when the turtle is knocked out.

upwards()
Stop drawing. untildownWhen you receive a call, nothing is drawn on the screen. However, the cursor movement still has an effect.
down()
Resume drawing after callingupwardscommands in betweenupwardsIndownstatement is not plotted, but after the commanddownThe statement is displayed normally.
latitude (width)
set to useaheadInbehindOrder.
color(*parameters)
Change the current color. The current color used to draw the lineaheadInbehind, and when filling the moldend fill()is calledstart fill().color can be given as a single color string (egcolor blue"),color ("Chocolate"),color ("Peru"),color("#a0df00"), ofcolor("#1dead1")).A triplet of floating-point RGB values (egcolor((0.1,0.5,0.9))ofcolor((95/255., 12/255., 9/255.))) can use.
start fill()
Used to fill shapes. First callstart fill()and continue drawing the outline of the shape you want to fill. Call when the form is completeend fill().whenstart fill()Invoke the command and the resulting polygon will be filled with the current color (the outer line color will also change). However, if an interior angle in the resulting polygon is greater than 180°, the resulting filled polygon will include only the first two segmentsstart fill()statement, forming a triangle.
