Trying to re-use some python 2 code in version 3 however hitting this snag (see attached code) any ideas?? Much appreciated!

--- connected to: 192.168.69.99
--- getting version information
Traceback (most recent call last):
File "/home/pi/Documents/prne/section6-CommunicatingWithNetworkDevices/show version-python3.py", line 83, in
device_version = get_version_info(session)
File "/home/pi/Documents/prne/section6-CommunicatingWithNetworkDevices/show version-python3.py", line 66, in get_version_info
version_output_parts = version_output_lines[1].split(',')

You can try to call the function with an encoded string:

bytes_str = str.encode()
