使用python图形模块turtle库绘制樱花、玫瑰、圣诞树代码

绘制樱花的代码：

import turtle# 设置画布大小turtle.setup(800, 600)# 画樱花的枝干def draw_branch(branch_len):if branch_len > 3:# 设置画笔粗细和颜色turtle.pensize(branch_len / 3)turtle.pencolor('brown')# 画右边的枝干turtle.forward(branch_len)turtle.right(20)draw_branch(branch_len - 15)# 画左边的枝干turtle.left(40)draw_branch(branch_len - 15)# 返回树干处turtle.right(20)turtle.backward(branch_len)# 画樱花的花瓣def draw_petal():turtle.pensize(2)turtle.pencolor('pink')turtle.fillcolor('pink')# 开始填充turtle.begin_fill()turtle.left(60)turtle.forward(30)turtle.right(60)turtle.circle(60, 120)turtle.right(60)turtle.forward(30)turtle.end_fill()# 移动画笔到指定位置def move_pen(x, y):turtle.penup()turtle.goto(x, y)turtle.pendown()# 主函数def main():# 隐藏画笔turtle.hideturtle()# 设置速度和角度turtle.speed(5)turtle.left(90)# 画樱花的枝干move_pen(0, -200)draw_branch(100)# 画樱花的花瓣move_pen(0, 0)for _ in range(6):draw_petal()turtle.left(60)# 关闭画布turtle.done()if __name__ == '__main__':main()

绘制玫瑰的代码：

import turtle# 设置画布大小turtle.setup(800, 600)# 画玫瑰def draw_rose():turtle.speed(10)turtle.pensize(2)turtle.pencolor('red')# 画玫瑰的花瓣for _ in range(18):turtle.forward(100)turtle.left(100)turtle.forward(100)turtle.right(160)# 画玫瑰的花蕊turtle.fillcolor('yellow')turtle.begin_fill()turtle.circle(10)turtle.end_fill()# 移动画笔到指定位置def move_pen(x, y):turtle.penup()turtle.goto(x, y)turtle.pendown()# 主函数def main():# 隐藏画笔turtle.hideturtle()# 画玫瑰move_pen(0, 0)draw_rose()# 关闭画布turtle.done()if __name__ == '__main__':main()

绘制圣诞树的代码：

import turtle# 设置画布大小turtle.setup(800, 600)# 画圣诞树def draw_tree():turtle.speed(10)turtle.pensize(3)turtle.pencolor('green')# 画树干turtle.fillcolor('brown')turtle.begin_fill()turtle.left(90)turtle.forward(100)turtle.right(90)turtle.backward(10)turtle.right(90)turtle.forward(10)turtle.right(90)turtle.backward(20)turtle.right(90)turtle.forward(10)turtle.right(90)turtle.backward(10)turtle.right(90)turtle.forward(100)turtle.end_fill()# 画树叶turtle.fillcolor('green')turtle.begin_fill()turtle.left(180)turtle.circle(100, -180)turtle.right(180)turtle.forward(100)turtle.right(60)turtle.circle(80, -180)turtle.right(180)turtle.forward(80)turtle.right(120)turtle.circle(80, -180)turtle.right(180)turtle.forward(80)turtle.right(60)turtle.circle(100, -180)turtle.end_fill()# 移动画
