Script explanation: I connect to network routers. I execute 3 commands and save output for later examination.
Problem:
I am getting an error related to "type error". I did not read or saved this as a file. The 'output' is being generated and stored in memory for the respective show commands. Please advise if you know how to get this resolved. Thank you.
myserver@ubuntu:~/scripts/trunk$ python3 mcast.py
Enter password(secured):
Password:
* SSH connection established to 172.18.120.185
Therefore I am puzzled on how to solve this.
script:
Question: Can I convert this form bytes to string - if at all possible?
I think I answered my own question:
I did
output_str = output.decode('utf-8')
Problem solved.

[hr]Update: to my surprise, I did:def olist(raw_show_data):
[b] print(type(raw_show_data)[/b])
#get output for show platform. I have the raw content of 'show' commands here, 3 different commands. Now I will split it:

print(olist_data[0])and the result is that indeed that is:<class 'bytes'>Question: Can I convert this form bytes to string - if at all possible?
