python處理blog檔案資料__python

下面是Python資料處理的題目說明與要求：
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 are displayed in time order. Please write one script with Python language to support the following features: Sort the logs in alphabetical order of process name, e.g.: halserver, processman, etc. Filter the logs according to process name, the output only show the interested logs, e.g.: “procman”, and hiding the rest. Statistics the number of log lines for each process.

這是機頂盒啟動並執行blog文字檔，開啟後部分截圖如下：

一看很亂，其實不應該用微軟的txt開啟，嘗試用notepad++開啟後，結構清楚了很多，部分截圖如下：

下面給出代碼：
第1題的代碼如下：

#coding=utf-8                                import re  f1=open('stblog.txt','r')f2=open('cc1.txt','w')list1=f1.readlines()list_process=[]    #定義列表存放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)):  #測試正則是否可行    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)

第2，3題代碼如下：

#coding=utf-8                              import re  f1=open('stblog.txt','r')f2=open('cc2.txt','w')list1=f1.readlines()list_process=[]      #定義列表存放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)):  #測試正則是否可行    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])   #將對應的process行添加到cc2.txt        count+=1print countf2.writelines(list2)
