def division():
    '''功能：分苹果'''
    print("\n=====================分苹果了=====================")
    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
    if remain>0:
        print(apple,"个苹果，平均分给",children,"个小朋友,每人分",result,"个，剩下",remain,"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：

• 实例02 模拟幼儿园分苹果（除数不能为0）

        division()
    except ZeroDivisionError:
        print("\n出错了~_~——苹果不能被0个小朋友分!")

、

运行结果：

• 实例03 模拟幼儿园分苹果（每个人至少分到一个苹果）
