基本功能

Turtle motion

函式	寫法
畫筆定位到座標(x,y)	turtle.goto(x,y)
向正方向運動 distance 長的距離	turtle.forward(distance)
向負方向運動 distance 長的距離	turtle.backward(distance)
向右偏 angle 度	turtle.right(angle)
向左偏 angle 度	turtle.left(angle)

函式	寫法
回到原點	turtle.home()
畫圓形 radius 為半徑，extent 為圓的角度	turtle.circle(radius, extent=None, steps=None)
以 speed 速度運動	turtle.speed(speed)

import turtle

turtle.speed(5)

turtle.goto(0,0)

for i in range(4):
    turtle.forward(100)
    turtle.right(90)

turtle.home()
turtle.circle(50,270)

Pen control

函式	寫法
落筆	turtle.pendown()
起筆	turtle.penup()
畫筆粗細	turtle.pensize(width)
畫筆顏色	turtle.pencolor(*args）
筆畫形狀	turtle.shape()

函式	寫法
填充顏色	turtle.fillcolor(*args)
開始填充	turtle.begin_fill()
結束填充	turtle.end_fill()
寫文字	turtle.write(arg, move=False, align=”left”, font=(“Arial”, 8, “normal”))

import turtle

turtle.pencolor('red')

turtle.pendown()

turtle.fillcolor('blue')

turtle.begin_fill()

for i in range(4):
    turtle.forward(200)
    turtle.right(90)
turtle.end_fill()
turtle.penup()
turtle.goto(100,-100)
turtle.write('Crossin程式設計教室')

Window control

函式	寫法
設定背景顏色	turtle.bgcolor(*args)
