小项目：猜数字游戏
🎮 项目介绍
我们来做一个经典的猜数字游戏！
游戏规则：
- 电脑随机生成一个 1-100 的数字
- 玩家猜测数字
- 电脑提示"太大"或"太小"
- 直到猜对为止，显示猜了多少次
📝 基础版本
先来实现最简单的版本：
python
import random
# 生成随机数
secret_number = random.randint(1, 100)
attempts = 0
print("=" * 40)
print(" 欢迎来到猜数字游戏！")
print(" 我想了一个 1-100 的数字")
print("=" * 40)
while True:
# 获取用户输入
guess = int(input("\n请猜一个数字："))
attempts += 1
# 判断
if guess < secret_number:
print("❌ 太小了，再大一点！")
elif guess > secret_number:
print("❌ 太大了，再小一点！")
else:
print(f"\n🎉 恭喜你猜对了！答案就是 {secret_number}")
print(f"你一共猜了 {attempts} 次")
break
print("\n游戏结束，感谢游玩！")🚀 进阶版本
让我们添加更多功能：
python
import random
def play_game():
"""游戏主函数"""
# 设置难度
print("\n请选择难度：")
print("1. 简单 (1-50，10次机会)")
print("2. 普通 (1-100，7次机会)")
print("3. 困难 (1-200，5次机会)")
choice = input("请选择 (1/2/3)：")
if choice == "1":
max_num, max_attempts = 50, 10
elif choice == "3":
max_num, max_attempts = 200, 5
else:
max_num, max_attempts = 100, 7
secret = random.randint(1, max_num)
attempts = 0
history = []
print(f"\n我想了一个 1-{max_num} 的数字")
print(f"你有 {max_attempts} 次机会，开始猜吧！\n")
while attempts < max_attempts:
remaining = max_attempts - attempts
try:
guess = int(input(f"[剩余 {remaining} 次] 请猜："))
except ValueError:
print("⚠️ 请输入有效的数字！")
continue
# 验证范围
if guess < 1 or guess > max_num:
print(f"⚠️ 请输入 1-{max_num} 之间的数字！")
continue
attempts += 1
history.append(guess)
if guess < secret:
diff = secret - guess
if diff > 20:
print("❄️ 太小了，差得远呢！")
else:
print("🔥 太小了，快接近了！")
elif guess > secret:
diff = guess - secret
if diff > 20:
print("❄️ 太大了，差得远呢！")

game.run()💡 学习要点
通过这个项目，你学会了：
- 随机数生成 -
random.randint() - 循环控制 -
while循环和break - 条件判断 -
if-elif-else - 异常处理 -
try-except - 列表操作 - 记录猜测历史
- 函数封装 - 将功能模块化
- 类的使用 - 面向对象编程
✏️ 扩展练习
试着添加这些功能：
- 计时功能 - 记录用时
- 排行榜 - 保存最佳成绩
- 双人模式 - 一人出题一人猜
- 提示系统 - 花费机会换取提示
