My script displaying text (config file) as expected on screen but with some extra characters when saved in a file /u/zxof Python Education

I have a simple script using nornir to run a command (config file) on a remote device, display it on screen and save it to a file.

The output looks fine on screen but certain lines of the saved config file has extra characters. I’ve tried different encodings without any luck.

I suppose I can clean up the extra characters but I would like to know the root cause of them problem, what’s causing the difference between the screen output and saved file.
