利用Python提取log有用信息并写入excel

由于log日志比较记录的事件比较多，很难直观分析自己想要的数据信息，因此就想把log中的有用信息提取出来，便于分析：

#coding=utf-8
import re
import os
import time
import xlwt
import datetime

path = r'C:\Users\qxrxxxx\Desktop\log'

downloadtime = time.strftime('%Y_%m_%d')
filename = 'NotificationTest_' + downloadtime + '.xls'
workbook = xlwt.Workbook(encoding='ascii')
worksheet = workbook.add_sheet('Comment')
workbook.save(filename)

font = xlwt.Font()  # Create the Font
font.bold = True
font.colour_index = 1
font.height = 0x00C8  # C8 in Hex (in decimal) = 10 points in height.
style = xlwt.XFStyle()  # Create the Style
style.font = font  # Apply the Font to the Style
pattern = xlwt.Pattern()  # Create the Pattern
pattern.pattern = xlwt.Pattern.SOLID_PATTERN  # May be: NO_PATTERN, SOLID_PATTERN, or 0x00 through 0x12
pattern.pattern_fore_colour = 23  # May be: 8 through 63. 0 = Black, 1 = White, 2 = Red, 3 = Green, 4 = Blue, 5 = Yellow, 6 = Magenta, 7 = Cyan, 16 = Maroon, 17 = Dark Green, 18 = Dark Blue, 19 = Dark Yellow , almost brown), 20 = Dark Magenta, 21 = Teal, 22 = Light Gray, 23 = Dark Gray, the list goes on...
style.pattern = pattern  # Add Pattern to Style
row = 1
for root,dirs,files in os.walk(path):
    for file in files:
        log_file = os.path.join(path,file)

        fp = open(log_file,encoding='utf-8')

        for line in fp.readlines():
            if "push messages count" in line:
                n = re.search(r'count:',line).span()[1]
                count = line[n:n+5].split(',')[0]
                print ('Count: '+line[n:n+5].split(',')[0])
                k = re.search(r'seId',line).span()[1]
                sendTime = line[k:].strip('\\').split('\"')[2].strip('\\')
                sendTime = datetime.datetime.strptime(sendTime,"%Y-%m-%d %H:%M:%S")
                # t = sendTime.timetuple()
                # timeStamp = int(time.mktime(t))
                # # h = int(sendTime[1].split(':')[0]) + 8
                # dateArray = datetime.datetime.utcfromtimestamp(timeStamp / 100 + 2880) 
                # sendTime = dateArray.strftime("%Y-%m-%d %H:%M:%S")
                sendTime = (sendTime + datetime.timedelta(hours=8)).strftime("%Y-%m-%d %H:%M:%S")


                print('SendTime: '+ sendTime )
                sendTime1 = datetime.datetime.strptime(sendTime, "%Y-%m-%d %H:%M:%S")
                receTime = line[1:].split(r']')[0].split('.')[0]
                receTime2 = datetime.datetime.strptime(receTime,"%Y-%m-%d %H:%M:%S")
                # print ('ReceTime: '+ receTime)
                delateTime = (receTime2 - sendTime1).seconds
                worksheet.write(row, 0, count)
                worksheet.write(row, 1, sendTime)
                worksheet.write(row, 2, receTime)
                worksheet.write(row, 3, delateTime)
                row = row + 1

worksheet.write(0, 0, "count", style)
worksheet.write(0, 1, "sendTime", style)
worksheet.write(0, 2, "receTime", style)
worksheet.write(0, 3, "delateTime", style)
worksheet.col(0).width = 2222
worksheet.col(1).width = 5555
worksheet.col(2).width = 5555
worksheet.col(3).width = 5555
workbook.save(filename)
