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:~#cdpython/
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#catrizhireplacelist.txt
['2010530181','2010530143','2010411116','2010156673','2001180073','2001180072','2001180071','2001180069','2001180068','2001180066','2001180065','2001180064','2001180059','2001180053','2001180051','2001180049','2001180048','2001180047','2001180046','2001180043','2001180042','2001180041','2001180040','2001180039','2001180038','2001180037','2001180036','2001180035','2001180034','2001180033','2020539277','2020539221','2020535288','2020260682','2010620102','2010570085','2010570070','2010500395','2010470053','2001610026','2001610025','2001180067','2001180045','2001180044','2001180001','2001020088','2001000583','2001000241','2000830359','2000632422','2000016602','2000015599','2000011716','2001180032','2001180031','2001180030','2001180029','2001180028','2001180027','2001180026','2001180025','2001180024','2001180023','2001180022','2001180021','2001180020','2001180019','2001180018','2001180017','2001180016','2001180015','2001180014','2001180013','2001180012','2001180011','2001180010','2001180009','2001180008','2001180007','2001180006','2001180005','2001180004','2001180003','2001180002','2001180000','1000019942','1000018830','1000018824','4000230040','4000219918','2020571702','2020260278','2010540076','2010540073','2010540068','2010505025','2010505024','2010500195','2010500191','2010500190','2010500189','2010500047','2010500046','2010419836','2010310986','2010310985','2001240027','2001180058','2001180057','2000831570','2000771823','2000771820','2000771677','2000771147','2000771116','2000771112','2000631255','2000021854','1000019921','1000018884','1000018875','1000018869','1000018842','1000017774','2060210271','2060210251','2001180052','2001180050','2000632723','2001180063','2001180061','2001180060','2001180056','2001180055','2001180054','100000000094646','10000000003629','10000000002412','10000000002328','10000000001057','100000000094709','100000000094680','100000000073254','10000000003949','10000000003947','10000000003556','10000000003554','10000000002167','10000000002066','10000000001096','10000000000786','10000000000782','10000000000594']
2、编写脚本代码
root@kali:~/python#catrizhitestsort.py
#!/usr/bin/python
#--*--coding:utf-8--*--
importre
befersort=[]#
midchang=[]
aftersort=[]
f1=file('rizhireplacelist.txt')#打开文件rizhireplacelist.txt
forpinf1.readlines():#逐行读取rizhireplacelist.txt文件
#printp
befersort=p#把逐行读取的内容存放到befersort
printbefersort
print'------------------------------------------------------'
count=len(befersort)#计算列表长度
printcount
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
#printmidchang
aftersort=[int(x)forxinmidchang]#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
printaftersort
root@kali:~/python#
3、实操脚本运行
root@kali:~/python#pythonrizhitestsort.py
