面向对象成员实现分页

class Pages:

    def __init__(self,nn):
        self.nn = nn          #获取输入的

    def start(self):
        s = (self.nn-1)*10+1  #分页开始

        return s

    def end(self):
        e = self.nn * 10 +1  #分页结束
        return e

listfen=[]
for li in range(100):
    listfen.append(li)  #添加数据到listfen中

while True:
    p = input("请输入分页码:")
    p = int(p)
    obj = Pages(p)

    print(listfen[obj.start():obj.end()])
    #切片  obj.start()和obj.end()分别获取的是返回值s，e

class Pages:

    def __init__(self,nn):
        self.nn = nn          #获取输入的
    @property
    def start(self):
        s = (self.nn-1)*10+1  #分页开始

        return s

    @property
    def end(self):
        e = self.nn * 10 +1  #分页结束
        return e

listfen=[]
for li in range(100):
    listfen.append(li)  #添加数据到listfen中

while True:
    p = input("请输入分页码:")
    p = int(p)
    obj = Pages(p)

    print(listfen[obj.start:obj.end])
    #切片  obj.start()和obj.end()分别获取的是返回值s，e
