A few suggestions for the python script:

- using format strings (f-strings) is a nice way in python to build
strings using variables.
- you can read and process a file in one pass if you iterate over the
open file itself instead of reading it into a variable and then
looping
- i had to change your strip code when i stopped using csv reader
- my python linter and auto-formater hate non-indendent comments
- i added a few lines to print cases where we don't get Ok responses.
