# 參數(shù)
SCREENSIZE=(600,600)
BLACK=(0,0,0,13)
# 初始化
pygame.init()
font = pygame.font.SysFont('宋體', 20)
screen = pygame.display.set_mode(SCREENSIZE)
surface = pygame.Surface(SCREENSIZE, flags=pygame.SRCALPHA)
pygame.Surface.convert(surface)
surface.fill(BLACK)
screen.fill(BLACK)

之后設置一下我們字體的相關內(nèi)容：

# 內(nèi)容
lib=[chr(i) for i in range(48,48+10)] + [chr(i) for i in range(97,97+26)]   # [0-9 a-z]
texts = [font.render(l, True, (0, 255, 0)) for l in lib]
cols = list(range(40))  # 字體15, 窗口600

最后在一個循環(huán)中，更新界面并繪制出代碼雨：

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            exit()
    pygame.time.delay(33)
    screen.blit(surface, (0, 0))
    for i in range(n:=len(cols)):
        text = random.choice(texts)
        # 字母掃描
        screen.blit(text, (i * 15, cols[i] * 15))
        cols[i] = (cols[i]+1)%40
    pygame.display.flip()

2. 完整代碼

完整代碼如下：

import pygame
import random
# 參數(shù)
SCREENSIZE=(600,600)
BLACK=(0,0,0,13)
# 初始化
pygame.init()
font = pygame.font.SysFont('宋體', 20)
screen = pygame.display.set_mode(SCREENSIZE)
surface = pygame.Surface(SCREENSIZE, flags=pygame.SRCALPHA)
pygame.Surface.convert(surface)
surface.fill(BLACK)
screen.fill(BLACK)
# 內(nèi)容
lib=[chr(i) for i in range(48,48+10)] + [chr(i) for i in range(97,97+26)]   # [0-9 a-z]
texts = [font.render(l, True, (0, 255, 0)) for l in lib]
cols = list(range(40))  # 字體15, 窗口600
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            exit()
    pygame.time.delay(33)
    screen.blit(surface, (0, 0))
    for i in range(n:=len(cols)):
        text = random.choice(texts)
        # 字母掃描
        screen.blit(text, (i * 15, cols[i] * 15))
        cols[i] = (cols[i]+1)%40
    pygame.display.flip()

截止到現(xiàn)在，我們已經(jīng)學會了用簡簡單單的30行代碼實現(xiàn)代碼雨，閃爍代碼以及線性掃描三種炫酷的特效了，相信大家在這個過程中也對 python 有了一個最初步的理解與認識，

到此這篇關于python 實現(xiàn)打印掃描效果詳情的文章就介紹到這了,更多相關python 打印掃描內(nèi)容請搜索腳本之家以前的文章或繼續(xù)瀏覽下面的相關文章希望大家以后多多支持腳本之家！
