Python Processing Blog File data

The following is the Python Data processing topic description and Requirements:
The attachment is a log file used to show running status of Set-top-box, and each line in the file follows the format of " LineNumber + time + ProcessName + (ProcessID) + Logs ", currently the Logs is displayed in time order. Write one script with Python language to support the following features:

1. Sort the logs in alphabetical order of process name, e.g.: Halserver, Processman, etc.
2. Filter the logs according to process name, the output is only show the interested logs, e.g.: "Procman", and hiding the rest.
3. Statistics the number of log lines for each process.

This is the set-top box to run the blog text file, open the following sections as follows:

A look very messy, in fact, should not be opened with the txt of Microsoft, try to open with notepad++, the structure is clear a lot, part of the following:

The following code is given:
The code for question 1th is as follows:

#coding=utf-8                                import re  f1=open(‘stblog.txt‘,‘r‘)f2=open(‘cc1.txt‘,‘w‘)list1=f1.readlines()list_process=[]    #定义列表存放Processres=‘\d\D\d\d:\d\d:\d\d\.\d{3}\s([a-z]+)‘for i in range(len(list1)):    list_process.append(re.findall(res,str(list1[i])))for i in range(len(list_process)):  #测试正则是否可行    if len(list_process[i])>1:        print ‘zheng ze fail‘#print len(list_process)    #print len(list1)#print list_process[141]#print list1[141]for m in range(len(list1)):      #冒泡排序    for n in range(m+1,len(list1)):        if cmp(list_process[m],list_process[n])>0:            list_process[m],list_process[n]=list_process[n],list_process[m]            list1[m],list1[n]=list1[n],list1[m]f2.writelines(list1)

2nd, the 3 question code is as follows:

#coding=utf-8                              import re  f1=open(‘stblog.txt‘,‘r‘)f2=open(‘cc2.txt‘,‘w‘)list1=f1.readlines()list_process=[]      #定义列表存放Processlist2=[]count=0res=‘\d\D\d\d:\d\d:\d\d\.\d{3}\s([a-z\.\-]+)‘for i in range(len(list1)):    list_process.append(re.findall(res,str(list1[i])))for i in range(len(list_process)):  #测试正则是否可行    if len(list_process[i])>1:        print ‘zheng ze fail‘s=raw_input("please input the log you interested:")for i in range(len(list_process)):    if list_process[i]==s.split():        list2.append(list1[i])   #将对应的process行添加到cc2.txt        count+=1print countf2.writelines(list2)
