面对对象的属性分页练习

class paging:
    def __init__(self, current_page):
        try:
            p = int(current_page)
        except Exception as e:
            p = 1
        self.page = p

    @property
    def start(self):
        val = (self.page-1) * 10
        return val

    @property
    def end(self):
        val = self.page * 10
        return val

while True:
    lis = []
    for i in range(1000):
        lis.append(i)
    p = input("请输入页码：")
    obj = paging(p)
    print(lis[obj.start:obj.end])
