循环python案例

当然，我可以给你介绍一些Python中的循环案例。Python提供两种主要的循环结构：for循环和while循环。

1. for循环案例：

   # 打印列表中的元素
   fruits = ["apple", "banana", "orange"]
   for fruit in fruits:
       print(fruit)

   # 计算列表中所有元素的和
   numbers = [1, 2, 3, 4, 5]
   total = 0
   for number in numbers:
       total += number
   print("总和为:", total)

   # 遍历字典中的键值对
   student_scores = {"Tom": 80, "Jerry": 90, "Alice": 95}
   for name, score in student_scores.items():
       print(name, "的分数是", score)

2. while循环案例：

   # 计算1到10的累加和
   total = 0
   num = 1
   while num <= 10:
       total += num
       num += 1
   print("总和为:", total)

   # 猜数字游戏
   secret_number = 42
   guess = int(input("猜一个数字: "))
   while guess != secret_number:
       if guess < secret_number:
           print("猜小了！")
       else:
           print("猜大了！")
       guess = int(input("再猜一个数字: "))
   print("恭喜你，猜对了！")
