一个简单的python分页小模块
#!/usr/bin/python3
# -*- coding: UTF-8 -*-
#url连接,countdatas表数据总行数,currentpage第几页(0是第一页),everpage每页多少行,beforlaterln前后长度
def pagestr(url,countdatas,currentpage,everpage,beforlaterln):

page=strbe+strmid+strlater
return "共"+str(countpage)+"页"+page
pages = pagestr('http://www.abc.com?',195,11,10,8)
print (pages)
运行后得到以下字符串
共20页<a class='num' href='http://www.abc.com?&p=0'>首页</a>
<a class='num' href='http://www.abc.com?&p=10'>上一页</a>
<a class='num' href='http://www.abc.com?&p=3'>4</a>
<a class='num' href='http://www.abc.com?&p=4'>5</a>
<a class='num' href='http://www.abc.com?&p=5'>6</a>
<a class='num' href='http://www.abc.com?&p=6'>7</a>
<a class='num' href='http://www.abc.com?&p=7'>8</a>
<a class='num' href='http://www.abc.com?&p=8'>9</a>
<a class='num' href='http://www.abc.com?&p=9'>10</a>
<a class='num' href='http://www.abc.com?&p=10'>11</a>
<span class='current'>12</span>
<a class='num' href='http://www.abc.com?&p=12'>13</a>
<a class='num' href='http://www.abc.com?&p=13'>14</a>
<a class='num' href='http://www.abc.com?&p=14'>15</a>
<a class='num' href='http://www.abc.com?&p=15'>16</a>
<a class='num' href='http://www.abc.com?&p=16'>17</a>
<a class='num' href='http://www.abc.com?&p=17'>18</a>
<a class='num' href='http://www.abc.com?&p=18'>19</a>
<a class='num' href='http://www.abc.com?&p=19'>20</a>
<a class='num' href='http://www.abc.com?&p=12'>下一页</a>
<a class='num' href='http://www.abc.com?&p=19'>尾页</a>
希望对大家有帮助,谢谢!
