My interpretation is that you want to read a file (list_of_devices.txt)
and this file contains names of other files and you want to read those
files as well and do something with them (read or print or whatever).

You can approach it like this: write a function to read a file and work
on it. Like this,

def fn(fname):
    with open(fname, "r") as f:
         try:
                # work with f
         except:
                print("error")

Then use this function in your code that you have writen. Like this

with open("list_of_devices.txt", "r") as reader:
     for item in reader:
         try:
                fn(item)
         except:
                print("error")

In the example that you gave, you have written contents of
"list_of_devices.txt" as

test1,test2

Take care to read them as comma separated. Or if you have control then
write them on separate lines.

Regards.
