Our first program will use the same general structure as the Pexpect program we have put together. We will loop over a list of devices and commands while using Paramiko instead of Pexpect. This will give us a good compare and contrast of the differences between Paramiko and Pexpect.
If you have not done so already, you can download the code, chapter2_3.py, from the book's GitHub repository, https://github.com/PacktPublishing/Mastering-Python-Networking-second-edition. I will list the notable differences here:
devices = {'iosv-1': {'ip': '172.16.1.20'}, 'iosv-2': {'ip': '172.16.1.21'}}
We no longer need to match the device prompt using Paramiko; therefore, the device dictionary can be simplified:
commands = ['show ...
