Python reading a file line by line and sending it to another Python script

Question

Good day.

Today i was trying to practice python and Im trying to make a script that reads the lines from a file containing only numbers and using said numbers as a parameter in another Python script.

Here at work i sometimes need to execute a python script called Suspend.py, ever time i excute this scripit i must type the following information:

Suspend.py suspend telefoneNumber

I have to do this procedure many times during the day and i have to do this for every number on the list, it is usually a very long list. SO i though on trying to make things a little bit faster and creat a Python script myself.

Thing is a just started learning Python on my own i kinda suck at it, so i have no idea on how to do this.

In one file i have the following numbers:

I want python to be able to read line by line and send this number to another file script together with the word "suspend" on the previously said python script.

You want to call the other script with arguments from the lines? — L3viathan

Would it not be better just to put/import your "reading" function into that script you are passing numbers into or is there some restrictions out of your hands? — MooingRawr

@L3viathan Yes, each number would be a new argument together with the word "suspend" — Otorrinolaringologista -man

@MooingRawr Well the "Suspend.py"script is not mine and i dont how it works and Im pretty sure i can`t change anything on it. — Otorrinolaringologista -man

If I understand you correctly:

import subprocess

with open("file_with_numbers.txt") as f:
    for line in f:
        subprocess.call(["python", "Suspend.py", "suspend", line.strip()])

Another question before i try executing this: The Suspend script also has 2 outputs, he can output OK or error, if i execute this script will i be able to see these outputs?

Look into subprocess.check_output.
