Error while running Python script via SSH

Question

I'm trying to run a Python script remotely via ssh local for a Linux machine but I'm getting an error when my script is reading a txt file, the script is running well without errors on my Python IDE.

I'm using ssh root@ip_adress python2 < script.py to run the script.

Part of my script where i'm reading the txt file:

import os
import smtplib

with open("file.txt") as fp:
     conteudo = fp.readlines()

conteudo = [linhas.strip() for linhas in conteudo]

Error:

Traceback (most recent call last):
File "<stdin>", line 4, in <module>
IOError: [Errno 2] No such file or directory: 'file.txt'

You'll have to rewrite the question, what is "script is running well outside the terminal" supposed to mean here? Does file.txt actually exist on the remote machine? — tink

@tink The file.txt is only on my pc. Do i need to have that file on my server? — pp fernandes

Of course. Executing a python script via ssh does NOT give it access to files on the machine from which it was invoked, it can only see things on the machine which it's running on. — tink

@tink Is there any way to make it use the file from my computer? And what should i use instead of ssh root@? I'm pretty new to this xD — pp fernandes

The main problem is that the file.txt only exist on my computer, so for that to work i would need a direct connection to my server to share my filesystem with it, but that's unsafe. So i decided to transfer the file.txt to my server using scp file.txt root@ip_adress:/path/where/the/file/is/going/toand then i had to change the path in the "with open() as" function to the path where my file was going to. After that i was able to execute the script without errors.
