Python 简单分页思路

一：

li = []

for i in range(1000):

    li.append(i)

while True:

    p = input('input page: ')

    p = int(p)

    start = (p-1) * 10

    end = p * 10

    print(li[start:end])

运行结果:

input page: 1

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

input page: 2

[10, 11, 12, 13, 14, 15, 16, 17, 18, 19]

input page: 5

[40, 41, 42, 43, 44, 45, 46, 47, 48, 49]

input page: 

二：

class Pagegenerate:

    def  __init__(self, current_page):

        try:

            p = int(current_page)

        except Exception as e:

            p = 1

        self.page = int(current_page)

    @property

    def start(self):

        val = (self.page-1) * 10

        return  val

    @property

    def end(self):

        val = self.page * 10

        return val

li = []

for i in range(1000):

    li.append(i)

while True:

    p = input("Enter the page to view: ")

    obj = Pagegenerate(p)

    print(li[obj.start:obj.end])

运行结果:

Enter the page to view: 2

[10, 11, 12, 13, 14, 15, 16, 17, 18, 19]

Enter the page to view: 5

[40, 41, 42, 43, 44, 45, 46, 47, 48, 49]
