try :

*** Test Cases ***

Launch py File
    ${result} =   evaluate   os.system('echo hello world')

if you want to validate it : you can add print as below:

*** Test Cases ***

Launch py File
    ${result} =   evaluate   print(os.system('echo hello world'))

the idea is that evaluate is the shortest way to run python in robot framework Starting from Robot Framework 3.2, modules used in the expression are imported automatically so there is no need to import the module

There is a much simpler way to run commands from a Robot Framework test, it is by using the OperatingSystem library. This library offers similar functionality as the import os does in Python.

In your case these three keywords that could be used:

An example:

*** Settings ***
Library     OperatingSystem

*** Test Case ***
Test case 1
    ${rc}   ${output} =     Run and Return RC and Output    echo "My string printed by a command"    # Any command could be called here.
    Log    ${rc}
    Should Be Equal As Integers     ${rc}   0    # Check if command execution was succesful.    
    Log    ${output}    # Log output of the command.

This would give the following output:

Thanks @Bence Kaulics, but i;m facing the issue i ran the command to login the below command (It will log into remote windows server and kill the particular process) ${rc} ${output} = Run and Return RC and Output echo "psexec.exe \\\\<SERVER IP> -u <Username> -p <Password> cmd /c D: ^& D:\\abc\\pch\\bin\\kill.exe <Process>" # Any command could be called here.

@Babu echo is part of my example command so you do not need that in your case. Also everything after # is a comment, so you can remove those as well.
