樱花飘落代码Python

以下是一个简单的樱花飘落的Python代码：

import random
import curses
from itertools import cycle

# 初始化游戏窗口
curses.initscr()
curses.curs_set(0)
win = curses.newwin(curses.LINES, curses.COLS, 0, 0)
win.nodelay(1)
win.keypad(1)
curses.noecho()
curses.cbreak()

# 定义樱花字符和颜色
sakura_chars = cycle(['❀', '✿', '❁', '✾', '❃'])
sakura_colors = cycle([
    curses.COLOR_RED,
    curses.COLOR_MAGENTA,
    curses.COLOR_CYAN,
    curses.COLOR_WHITE,
    curses.COLOR_YELLOW
])

# 定义樱花的类
class Sakura:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.char = next(sakura_chars)
        self.color = next(sakura_colors)
        self.speed = random.randint(1, 5)

    def drop(self):
        self.y += self.speed
        if self.y >= curses.LINES - 1:
            self.y = 0
            self.x = random.randint(0, curses.COLS - 1)
            self.char = next(sakura_chars)
            self.color = next(sakura_colors)
            self.speed = random.randint(1, 5)

    def draw(self):
        win.addstr(int(self.y), int(self.x), self.char, curses.color_pair(self.color))

# 初始化颜色
curses.start_color()
for i in range(1, curses.COLORS):
    curses.init_pair(i, i, curses.COLOR_BLACK)

# 创建樱花列表
sakuras = []
for i in range(100):
    sakuras.append(Sakura(random.randint(0, curses.COLS - 1), random.randint(0, curses.LINES - 1)))

# 游戏循环
while True:
    # 处理输入事件
    key = win.getch()
    if key == ord('q'):
        break

    # 清空屏幕
    win.erase()

    # 飘落樱花
    for sakura in sakuras:
        sakura.drop()
        sakura.draw()

    # 刷新屏幕
    win.refresh()

# 清理游戏窗口
curses.nocbreak()
win.keypad(0)
curses.echo()
curses.endwin()

运行该代码，会出现一个全屏的樱花飘落效果。用户可以按下`q`键退出游戏。

请注意，该代码需要在终端中运行，而不是在IDLE或者其他IDE中。
