1. Learn some properties of Python Turtle before you start drawing
Turtle. forward(distance) : move distance pixel length to the current paintbrush turtle.backward(distance) : move distance pixel length to the opposite direction of the current paintbrush turtle.right(degree) : Left (degree) : Counterclockwise degree turtle.left(degree) : counterclockwise degree Turtle.pendown () : Draws while moving, also draws turtle.goto(x,y) by default: Turtle.penup () : Draws a circle with a radius of positive (negative), indicating that the center of the circle is to the left (right) of the brush setx() : Sety () : Moves the current x axis to the specified position sety() : moves the current Y axis to the specified position Setheading (Angle) : sets the current orientation to Angle Home () : sets the current brush position to the origin, facing east. Dot (r) : Draws a dot with the specified diameter and color turtle.fillcolor(colorString) : Color (color1, color2): Also set pencolor=color1, Fillcolor =color2 Turtle.filling (): Returns whether it is currently filling or not turtle.begin_fill() : Ready to start filling the graph turtle.end_fill() : complete filling turtle.hideturtle() : Hide the pen's Turtle shape turtle.showTurtle () : Shows the pen's Turtle shapeCopy the codeTo draw your favorite cat, let’s draw a cat to play with
