先画一个爱心,
源代码:
#!/usr/bin/env python # -*- coding:utf-8 -*- import turtle import time # 画心形圆弧 def hart_arc(): for i in range(200): turtle.right(1) turtle.forward(2) def move_pen_position(x, y): turtle.hideturtle() # 隐藏画笔(先) turtle.up() # 提笔 turtle.goto(x, y) # 移动画笔到指定起始坐标(窗口中心为0,0) turtle.down() # 下笔 turtle.showturtle() # 显示画笔 # 初始化 turtle.setup(width=800, height=500) # 窗口(画布)大小 turtle.color('red', 'pink') # 画笔颜色 turtle.pensize(3) # 画笔粗细 turtle.speed(1) # 描绘速度 # 初始化画笔起始坐标 move_pen_position(x=0,y=-180) # 移动画笔位置 turtle.left(140) # 向左旋转140度 turtle.begin_fill() # 标记背景填充位置 # 画心形直线( 左下方 ) turtle.forward(224) # 向前移动画笔,长度为224 # 画爱心圆弧 hart_arc() # 左侧圆弧 turtle.left(120) # 调整画笔角度 hart_arc() # 右侧圆弧 # 画心形直线( 右下方 ) turtle.forward(224) turtle.end_fill() # 标记背景填充结束位置 # 点击窗口关闭程序 window = turtle.Screen() window.exitonclick()
