实例01 模拟幼儿园分苹果:
def division(): '''功能:分苹果''' print("\n==============分苹果了================\n") apple = int(input("请输入苹果的个数:")) children = int(input("请输入来了几个小朋友:")) result = apple // children remain = apple - result*children #计算余下苹果 if remain > 0: print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。") else: print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。") if __name__ == '__main__': division()
运行结果如下:
实例02 模拟幼儿园分苹果:(除数不能为0)
def division(): '''功能:分苹果''' print("\n==============分苹果了================\n") apple = int(input("请输入苹果的个数:")) children = int(input("请输入来了几个小朋友:")) result = apple // children remain = apple - result*children #计算余下苹果 if remain > 0: print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。") else: print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。") if __name__ == '__main__': try: division() except ZeroDivisionError: print("\n出错了~_~ —— 苹果不能被0个小朋友分!")
运行结果如下:
实例03 模拟幼儿园分苹果:(每个人至少分到一个苹果)
def division(): '''功能:分苹果''' print("\n==============分苹果了================\n") apple = int(input("请输入苹果的个数:")) children = int(input("请输入来了几个小朋友:")) if apple < children: raise ValueError("苹果太少了,不够分...") #抛出异常(reason) result = apple // children remain = apple - result*children #计算余下苹果 if remain > 0: print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。") else: print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。") if __name__ == '__main__': try: division() except ZeroDivisionError: print("\n出错了~_~ —— 苹果不能被0个小朋友分!") except ValueError as e: print("\n出错了 ~_~ ——", e)
运算结果如下:
实例04 模拟幼儿园分苹果:(应用断言调试)
def division(): '''功能:分苹果''' print("\n==============分苹果了================\n") apple = int(input("请输入苹果的个数:")) children = int(input("请输入来了几个小朋友:")) assert apple >= children, "苹果不够分" #应用断言调试 result = apple // children remain = apple - result*children #计算余下苹果 if remain > 0: print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。") else: print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。") if __name__ == '__main__': division()
运行结果如下:
