python 实现提取log文件中的关键句子,并进行统计分析

利用python开发了一个提取sim.log 中的各个关键步骤中的时间并进行统计的程序：

#!/usr/bin/python2.6
import re,datetime
file_name='/home/alzhong/logs/qtat1/R2860.01.13/sim-applycommitrollback-bld1.log'
file=open(file_name,'r')
acnum=[];time_res=[];lnum=0
def trans_time(time):
 t1=datetime.datetime.strptime(time,'％y/％m/％d ％H:％M:％S')
 return t1
for (num,line) in enumerate(file):

if(re.search(r'^(.*)BEGINNING SIM PROCEDURE(.*)$',line)):
   m=re.search(r'^(.*)BEGINNING SIM PROCEDURE(.*)$',line)
   print 'Step ％d:'％(lnum), m.group(0);lnum+=1
   acnum.append(trans_time(line[0:17]))
 elif(re.search(r'^(.*)CP_W(.*)$', line)):
   m=re.search(r'^(.*)CP_W(.*)$', line)
   print 'Step ％d:'％(lnum), m.group(0);lnum+=1
   acnum.append(trans_time(line[0:17]))

   print 'Step ％d:'％(lnum), m.group(0);lnum+=1
   acnum.append(trans_time(line[0:17]))
 elif(re.search(r"^(.*)RESUMING SIM PROCEDURE(.*)$",line)):
   m=re.search(r"^(.*)RESUMING SIM PROCEDURE(.*)$",line)
   print 'Step ％d:'％(lnum), m.group(0);lnum+=1
   acnum.append(trans_time(line[0:17]))

file.close()

 time_res.append(((acnum[8]-acnum[7])+(acnum[10]-acnum[9])+(acnum[13]-acnum[11])).seconds/60)
 print "\n3). sim --proc update --action apply to \"CP_WARNING\" ％s mins" ％(time_res[0])
 print "4). sim --proc update --action resume to \"VERIFY_SOFTWARE\" ％s mins"％(time_res[1])
 print "5). sim --proc update --action resume to \"COMMIT\" ％s mins"％(time_res[2])
 print "8). Backout from RXX to RXX ％s mins"％(time_res[3])
elif(re.search(r"^(.*)rollback(.*)$",file_name)):
