python ssh paramiko保存到文件

Question

我想將ssh連接的所有輸出保存到文件中。 ssh連接工作正常，對於標准輸出也可以輸出。 我想為文件中的每個連接單獨創建一個文件。 我將輸出行更改為下面的行，也將其移到上面

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

什么東西少了？

我收到此錯誤：

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

而且它只是不保存輸出。 文件已創建，但為空白。

僅在Python3中會發生這種情況，因為except現在期望的是一個類，它是BaseException的子類。 而整數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提出了其他一些錯誤，但是在嘗試評估except 10060語句時，錯誤處理except 10060 。
