一、模拟幼儿园分苹果

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()

运行结果如下：

 

 二、模拟幼儿园分苹果（除数不能为零）

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__':
    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：

 

 三、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===================")
    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……")
    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__':
    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)

运行结果如下：

 

 四、应用断言调试

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："))
    assert apple>children,"苹果不够分"
    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()

运行结果如下：
