pycharm樱花代码

以下是一个使用PyCharm编写的绘制樱花树的Python代码，它包括绘制樱花的落叶花瓣、掉落的花瓣、给樱花树添加树枝、添加绘画背景颜色的绘制和选取各种样式的颜色等功能。你可以在PyCharm中打开并运行它。

import turtle
import random

# 绘制樱花的落叶花瓣
def petal(t, petal_radius, petal_length):
    angle = 360 / petal_number
    for i in range(petal_number):
        t.circle(petal_radius, angle)
        t.left(180 - angle)
        t.circle(petal_radius, angle)
        t.right(180 + angle)
    t.right(90)
    t.forward(petal_length)

# 绘制掉落花瓣功能
def petal_fall(t, petal_radius, petal_length):
    t.penup()
    t.setpos(random.randint(-200, 200), 200)
    t.pendown()
    petal(t, petal_radius, petal_length)

# 给樱花树添加树枝
def branch(t, branch_length):
    if branch_length > 10:
        angle = random.randint(20, 40)
        scale = random.uniform(0.6, 0.8)
        t.pensize(branch_length / 10)
        t.forward(branch_length)
        t.right(angle)
        branch(t, branch_length * scale)
        t.left(angle * 2)
        branch(t, branch_length * scale)
        t.right(angle)
        t.backward(branch_length)

# 给樱花树添加绘画背景颜色的绘制
def draw_sky(t):
    t.penup()
    t.setpos(-300, 300)
    t.pendown()
    t.begin_fill()
    t.fillcolor("#87CEEB")
    for i in range(4):
        t.forward(600)
        t.right(90)
    t.end_fill()

# 选取各种样式的颜色
def random_color():
    r = random.randint(128, 255)
    g = random.randint(0, 128)
    b = random.randint(0, 128)
    return (r, g, b)
