使用python图形模块turtle库绘制樱花、玫瑰、圣诞树代码实现

以下是使用Python的turtle库绘制樱花、玫瑰和圣诞树的代码实现。

樱花：

import turtle def draw_branch(branch_len): if branch_len > 3: if branch_len < 30: turtle.pencolor("pink") else: turtle.pencolor("brown") turtle.forward(branch_len) turtle.right(20) draw_branch(branch_len - 15) turtle.left(40) draw_branch(branch_len - 15) turtle.right(20) turtle.penup() turtle.backward(branch_len) turtle.pendown() def draw_sakura(): turtle.speed(0) turtle.penup() turtle.left(90) turtle.backward(200) turtle.pendown() draw_branch(100) turtle.exitonclick() draw_sakura() 

玫瑰：

import turtle def draw_flower(): turtle.color("red") turtle.begin_fill() turtle.left(50) turtle.forward(133) turtle.circle(50, 180) turtle.right(140) turtle.circle(50, 180) turtle.forward(133) turtle.end_fill() def draw_stem(): turtle.color("green") turtle.right(90) turtle.forward(200) def draw_rose(): turtle.penup() turtle.backward(100) turtle.pendown() draw_flower() draw_stem() turtle.exitonclick() draw_rose() 

圣诞树：

import turtle def draw_tree(branch_len): if branch_len > 5: turtle.forward(branch_len) turtle.right(20) draw_tree(branch_len - 15) turtle.left(40) draw_tree(branch_len - 15) turtle.right(20) turtle.backward(branch_len) def draw_star(): turtle.color("yellow") turtle.begin_fill() for _ in range(5): turtle.forward(50) turtle.right(144) turtle.end_fill() def draw_christmas_tree(): turtle.speed(0) turtle.penup() turtle.left(90) turtle.backward(200) turtle.pendown() turtle.color("green") turtle.begin_fill() turtle.forward(100) turtle.right(90) turtle.forward(20) turtle.right(90) turtle.forward(20) turtle.right(90) turtle.forward(20) turtle.left(90) turtle.forward(50) turtle.left(90) turtle.forward(20) turtle.left(90) turtle.forward(20) turtle.right(90) turtle.forward(100) turtle.end_fill() turtle.penup() turtle.left(90) turtle.forward(120) turtle.left(90) turtle.pendown() draw_tree(100) turtle.penup() turtle.backward(100) turtle.pendown() draw_star() turtle.exitonclick() draw_christmas_tree() 

这些代码可以在Python环境中运行，并使用turtle库来绘制相应的图形。
