我想使用python脚本打印此文件中的所有IPv4地址。目前我只能使用下面的python脚本打印第一个IPv4（10.0.6.106）地址。

ip = open（“ip.txt”）。read（）。split（“IPv4”）[1] .split（“：”）[1] .split（“\ n”）[0 ]。跳闸（） print ip

请帮我打印所有IPv4地址。

Answer 1

这应该这样做：

with open('ip.txt') as ip:
    for line in ip:
        if line.startswith('IPv4 Address'):
            line = line.split(':')
            print line[1].strip()

我需要根据帧名来整理数据。在上面我有4个帧名称TX2TX，Rx2Tx，Rx2Bsave，Bsave2Tx。我需要识别这些框架名称并接收其数据并创建Excel工作表并写入相应的工作表。

以下是为此目的而编写的代码。我可以创建excel表，但我无法写入单独的表。

 import xlwt

 wbk = xlwt.Workbook()    

 row = 4 # row counter
col = 0
sheet_number = 0

f = open('Log1.txt')

 for line in f:
    if 'Frame Name' in line:
         sheet_number += 1
         sheetname = line.split(':')[-1]

        sheet = wbk.add_sheet(sheetname)
        wbk.active_sheet = 0

      L = line.split('#')
        for i,c in enumerate(L):        
       sheet.write(row,i,c)
     row += 1

 wbk.save('example.xls')
