我有一个文本文件，它是从我与Netmiko一起运行的命令输出的，用于从思科WLC中检索导致我们WiFi网络受到干扰的数据。我从原始的600k代码行中删除了我需要的内容，直到这样的几千行：
AP Name.......................................... 010-HIGH-FL4-AP04

目标是最终得到一个csv文件，删除“AP名称...”＆＃39;并将与剩余信息保持在同一行的内容放在下一行。问题是有些人在AP名称下面有两行，有些有1或没有。我已经在这里工作了8个小时，找不到实现这一目标的最佳方法。
这是我尝试使用的最新版本的代码，是否有任何使这项工作的建议？我只想要一些我可以在excel中加载并使用以下内容创建报告的内容：
with open(outfile_name, 'w') as out_file:
with open('wlc-interference_raw.txt', 'r')as in_file:
#Variables
_ap_name = ''
_temp = ''
_flag = False
for i in in_file:
if 'AP Name' in i:
#write whatever was put in the temp file to disk because new ap now
#add another temp variable in case an ap has more than 1 interferer and check if new AP name
out_file.write(_temp)
out_file.write('\n')
#print(_temp)
_ap_name = i.lstrip('AP Name.......................................... ')
_ap_name = _ap_name.rstrip('\n')
_temp = _ap_name
#print(_temp)
elif '----' in i:
pass
elif 'Class Type' in i:
pass
else:
line_split = i.split()
for x in line_split:
_temp += ','
_temp += x
_temp += '\n'
答案 0 :(得分：0)
我认为你最好的选择是读取文件的所有行，然后分成以AP名称开头的部分。然后你可以解析每个部分。

提示：
您不需要Python来编写CSV，您可以使用命令行输出到文件
python script.py > output.csv
