  高度还原影视剧中黑客桌面代码雨，而且是动态的！

  使用的库：random ， pygame ， sys 。

  代码如下：

import random
import pygame 
from pygame.locals import *
from sys import exit

PANEL_width = 1920
PANEL_highly = 1080
FONT_PX = 40

pygame.init()

winSur = pygame.display.set_mode((PANEL_width, PANEL_highly), FULLSCREEN, 32)

font = pygame.font.SysFont("SimHei", 35)

bg_suface = pygame.Surface((PANEL_width, PANEL_highly), flags=pygame.SRCALPHA)
bg_suface.fill(pygame.Color(0, 0, 0, 20))

winSur.fill((0, 0, 0))

letter = [chr(i) for i in range(97, 123)]

texts = [font.render(char, True, (0, 255, 0)) for char in letter[:20]]

column = PANEL_width // FONT_PX
drops = [0] * column

try:
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                exit()
            elif event.type == pygame.KEYDOWN and event.key == pygame.K_SPACE:
                exit()

        pygame.time.delay(30)

        winSur.blit(bg_suface, (0, 10))

        for i in range(column):
            text = random.choice(texts)
            winSur.blit(text, (i * FONT_PX, drops[i] * FONT_PX))
            drops[i] += 1
            if drops[i] * FONT_PX > PANEL_highly or random.random() > 0.95:
                drops[i] = 0

        pygame.display.flip()

except Exception as e:
    print(f"发生错误: {e}")
    pygame.quit()
