Question

我想保存到ssh连接的所有输出文件。 ssh连接工作正常，输出对于标准输出也是正常的。我想为文件中的每个连接创建一个文件。我已将输出行更改为下面的行，并将其移到

之上

output_filename = ip_address + ".txt"
file = open(output_filename, 'w')
file.write(output.decode)
file.close()

缺少什么？

我收到此错误：

line 100, in fractal
    except 10060:
TypeError: catching classes that do not inherit from BaseException is not allowed

它只是不保存输出。文件已创建，但为空白。

这只发生在Python3中，因为except现在需要一个类BaseException的类。并且整数10060不是。

>>> try:
...   raise ValueError
... except 10080:
...   print('dfsdf')
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ValueError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 3, in <module>
TypeError: catching classes that do not inherit from BaseException is not allowed

因此Paramiko引发了一些其他错误，但错误处理在尝试评估except 10060语句时死亡。

python ssh paramiko保存到文件
