前言
粉色系最爱！Python樱花树等你获取~
哈喽小伙伴们好久不见啦，最近樱花开得好美吖，博主想和大家一起分享春天的快乐，一起来看看博主画的樱花树吧！
技术需求
在使用Python绘制樱花树之前，让我们先深入了解turtle库的基础知识。
Turtle库是Python中一个重要的内置绘图包，提供了丰富的绘图工具和功能。掌握Turtle绘图后，你可以创作出各种图案。
1.1 Turtle画板设置
使用turtle.screensize()函数可以调整Turtle画板的大小：
turtle.screensize(width, height, bg)
width: 设置画板宽度。height: 设置画板高度。bg: 设置画布背景颜色。
1.2 Turtle画笔控制
Turtle画笔常用的几个函数包括：
① turtle.penup(): 抬起画笔，移动时不留下痕迹。
② turtle.pendown(): 放下画笔，与penup()相对，放下后继续绘图并留下痕迹。
③ turtle.pensize(size): 设置画笔粗细。
④ turtle.pencolor(color): 设置画笔颜色，可查阅Python支持的所有颜色。
⑤ turtle.hideturtle(): 隐藏画笔，隐藏后绘图时看不到画笔。
1.3 Turtle基本绘图操作
绘图过程中常用的一些移动函数有：
① turtle.forward(distance): 向前移动指定距离。
② turtle.backward(distance): 向后移动指定距离。
③ turtle.left(angle): 向左旋转指定角度。
④ turtle.right(angle): 向右旋转指定角度。
⑤ turtle.speed(speed): 设置绘图速度，范围为0（最快）到10（最慢）。
1.4 Turtle图形填色
完成图形绘制后，可使用turtle.fillcolor()进行填色：
turtle.begin_fill() # 开始填充
turtle.fillcolor(color) # 设置填充颜色
turtle.end_fill() # 结束填充
1.5 Turtle文本输出
使用turtle.write()函数可以在绘图完成后添加文本：
turtle.write(text, move=False, align="left", font=("宋体", 8, "normal"))
text: 要写入的文本内容。move: 是否将画笔移动到文本右下角，默认为False。align: 文本对齐方式，可选值为"left"、"center"、"right"。font: 字体设置，三元组形式(fontname, fontsize, fonttype)，例如("宋体", 8, "normal")。

代码分析
在对turtle库进行初步了解后，我们正式进入今天的主题！
2.1 樱花类
既然是樱花树，自然少不了樱花的绘制。在此，我选择了五片花瓣的经典樱花设计
def flower(): tu.hideturtle() tu.pensize(2) tu.pencolor("pink")flowersize = ra.randint(1, 5) for _ in range(5): tu.forward(flowersize)tu.backward(flowersize)tu.right(72)
2.2 樱花树
完成樱花的绘制后，接下来我们将通过递归方法来构建樱花树
def tree(n, k):tu.pendown() tu.pencolor("black")tu.pensize(n / 4)tu.forward(k) if n > 0:r = ra.random() * 10 + 10l = ra.random() * 10 + 10x = k * (ra.random() * 0.25 + 0.7) tu.right(r)tree(n - 1, x)tu.left(l + r)tree(n - 1, x)tu.right(l)# Continue the tree structure here...
2.3 主函数
最后，我们需要一个主函数来整合并实现完整的樱花树
tu.setup(800, 480)
tu.bgcolor("lavenderblush")
tu.hideturtle()
tu.tracer(0)
tu.penup()
tu.goto(0, -150)
tu.pendown()
tu.left(90)
tree(12, 50)
for _ in range(99):tu.penup()tu.goto(ra.randint(-150, 150), ra.randint(-150, 0))tu.pendown()flower()
2.4 樱花林
单棵樱花树显然不足以构成美景，利用循环语句，我们可以创建一片美丽的樱花林
for _ in range(20):tu.penup() tu.goto(ra.randint(-300, 300), ra.randint(-150, 0))tu.pendown()tu.left(90) tree(8, 30)tu.setheading(0)# Continue the forest creation here...
