为了编写一个网络空间安全的小游戏，我们可以模拟一些基本的网络安全概念，如防火墙、入侵检测、病毒清理等。以下是一个简单的Python小游戏示例，其中玩家需要保护自己的网络免受攻击。

python复制代码

 

import random  class Network:  def __init__(self):  self.security_level = 100  self.firewall_strength = 50  self.antivirus_strength = 50  self.logs = []  def log(self, message):  self.logs.append(message)  print(message)  def attack(self, attack_type):  if attack_type == "malware":  damage = random.randint(10, 50)  if self.antivirus_strength > damage:  self.log("Antivirus detected and blocked malware attack!")  else:  self.security_level -= damage  self.log(f"Malware attack successful! Security level reduced by {damage}.")  elif attack_type == "hacking":  damage = random.randint(10, 30)  if self.firewall_strength > damage:  self.log("Firewall blocked the hacking attempt!")  else:  self.security_level -= damage  self.log(f"Hacking attempt successful! Security level reduced by {damage}.")  else:  self.log("Unknown attack type!")  def reinforce_firewall(self):  if self.security_level >= 10:  self.security_level -= 10  self.firewall_strength += 10  self.log("Firewall reinforced! Strength increased by 10.")  else:  self.log("Not enough security level to reinforce firewall.")  def update_antivirus(self):  if self.security_level >= 15:  self.security_level -= 15  self.antivirus_strength += 15  self.log("Antivirus updated! Strength increased by 15.")  else:  self.log("Not enough security level to update antivirus.")  def main():  network = Network()  game_over = False  while not game_over:  print("\nCurrent Security Level:", network.security_level)  print("Firewall Strength:", network.firewall_strength)  print("Antivirus Strength:", network.antivirus_strength)  print("\n1. Reinforce Firewall")  print("2. Update Antivirus")  print("3. View Logs")  print("4. Exit Game")  choice = input("Enter your choice: ")  if choice == "1":  network.reinforce_firewall()  elif choice == "2":  network.update_antivirus()  elif choice == "3":  print("\nLogs:")  for log in network.logs:  print(log)  elif choice == "4":  game_over = True  print("Exiting game...")  else:  print("Invalid choice! Please try again.")  if network.security_level <= 0:  game_over = True  print("\nGame Over! Your network has been compromised!")  if __name__ == "__main__":  main()

在这个游戏中，玩家可以选择加固防火墙或更新杀毒软件来提高网络安全。每次加固或更新都会消耗一定的安全级别。游戏会随机生成攻击，如果防火墙或杀毒软件不足以抵挡攻击，安全级别会降低。当安全级别降至0时，游戏结束。玩家还可以查看日志以了解之前发生的事件。
