2、編寫(xiě)腳本代碼
root@kali:~/python# cat rizhitestsort.py
#!/usr/bin/python
#--*-- coding:utf-8 --*--
import re
befersort = []#
midchang = []
aftersort= []
f1 = file('rizhireplacelist.txt')#打開(kāi)文件rizhireplacelist.txt
for p in f1.readlines():#逐行讀取rizhireplacelist.txt文件
# print p
befersort = p#把逐行讀取的內(nèi)容存放到befersort
print befersort
print '------------------------------------------------------'
count = len(befersort)#計(jì)算列表長(zhǎng)度
print count
close.f1()
mode = re.compile(r'\d+')#\d是匹配數(shù)字字符[0-9]，+匹配一個(gè)或多個(gè)，放在一起是匹配一個(gè)或多個(gè)數(shù)字字符，比如：'1‘、'34‘、'9999‘
midchang = mode.findall(befersort)#對(duì)befersort列表進(jìn)行正則匹配，并存儲(chǔ)到midchang
#print midchang
aftersort = [int(x) for x in midchang]#讀取被正則匹配成功的每個(gè)數(shù)字，并存儲(chǔ)到aftersort中
aftersort.sort()#對(duì)aftersort進(jìn)行正序排列
print aftersort

3、實(shí)操腳本運(yùn)行
