python之实现自定义分页功能

# 实现自定义分页
import math
def custom_paginator(current_page, num_page, max_page=10): 
 middle = math.ceil(max_page / 2) 
 # 一种特殊情况 
 # 总页数,小于最大页数 
 if num_page < max_page: 
 start = 1 
 end = num_page 
 else: 
 # 一般情况 
 # 当前页在头部的时候 
 if current_page <= middle: 
 start = 1 
 end = max_page 
 # 当前页在中间时 
 elif (current_page > middle) & (current_page < num_page - middle + 1): 
 start = current_page - middle 
 end = current_page + middle - 1 
 else: 
 # 当前页在尾部 
 start = num_page - max_page + 1 
 end = num_page 
 return start, end
