python - Python / Netmiko：在切换日志中查找故障

Question

我试图让我的程序从交换机查看日志，看看其中是否出现“单词”。

从交换机中提取日志的部分有效，但检查坏词的部分无效。我能够使代码适用于 txt 文件，但不适用于输出。

我的代码：

    net_connect.enable()
    output = net_connect.send_command('show log')
    print(output)
    filename = ('log_files/SW_'+ip_addresses[count]+'_'+TNOW+'.txt')

    SAVE_FILE = open(filename, 'w+')
    SAVE_FILE.write(output)

    print(filename)
    textring = (output)

    with textring as infile:
        text = infile.read()
    words = ['flapping', 'Unexpected', 'down']
    for word in words:
        if word in text:
            print('success')
            with open('warnings/SW_WARNING.txt', 'w+') as save_file:
                save_file.write(text)
            break

这是我得到的错误：

    Traceback (most recent call last):
    File "script.py", line 150, in <module>
    with textring as infile:
    AttributeError: __enter__

有谁知道如何让代码查看开关的输出，因为它还没有变成一个文件？

Answer 1

# Eliminate as unnecessary/error on your "with" statement
# textring = (output)
# with textring as infile:
#    text = infile.read()

for word in ['flapping', 'Unexpected', 'down']:
    if word in output:
        print('success')
        with open('warnings/SW_WARNING.txt', 'w+') as save_file:
            save_file.write(output)
        break
