Python实现对特定列表进行从小到大排序操作示例

本文实例讲述了Python实现对特定列表进行从小到大排序操作。分享给大家供大家参考，具体如下：

1、在系统内新建文件rizhireplacelist.txt

root@kali:~# cd python/
root@kali:~/python# ls
111.txt           listsalaryver2.py  readfile2.py            rizhireplacelist.txt  rizhi.txt            tixingexcel.txt     tixingsort.txt
contact_list.txt  listshop.py        replacefile1.py         rizhireplace.txt      shoplist.txt         tixinglistsort.py   tixing.txt
listbuy.py        manageserach.py    rizhireplaceexcel.txt   rizhisort.py          test.py              tixinglistsort.txt
listsalary.py     readfile1.py       rizhireplacefenhao.txt  rizhitestsort.py      tixingexcelsort.txt  tixinglist.txt
root@kali:~/python#cat rizhireplacelist.txt

2、编写脚本代码

root@kali:~/python# cat rizhitestsort.py
#!/usr/bin/python
#--*-- coding:utf-8 --*--
import re
befersort = []#
midchang = []
aftersort= []
f1 = file('rizhireplacelist.txt')#打开文件rizhireplacelist.txt
for p in f1.readlines():#逐行读取rizhireplacelist.txt文件
#  print p
  befersort = p#把逐行读取的内容存放到befersort
  print befersort
print '------------------------------------------------------'
count = len(befersort)#计算列表长度
print count
close.f1()
mode = re.compile(r'\d+')#\d是匹配数字字符[0-9]，+匹配一个或多个，放在一起是匹配一个或多个数字字符，比如：'1‘、'34‘、'9999‘
midchang = mode.findall(befersort)#对befersort列表进行正则匹配，并存储到midchang
#print midchang
aftersort = [int(x) for x in midchang]#读取被正则匹配成功的每个数字，并存储到aftersort中
aftersort.sort()#对aftersort进行正序排列
print aftersort
root@kali:~/python#

3、实操脚本运行

root@kali:~/python# python rizhitestsort.py
