Run a command with arguments in python

[Raviteja_1]

Hello All
I am want to run a command "Merge -i file1.txt -i file2.txt -o out.txt" using python script. Here Merge is a exe file located in different path and file1, file2 are input to the exe file and out is output file. Can anyone suggest me out to run this command in python script.
Thank you

I do this so frequently that I created a bit of library code. It's so short that it should need no explanation.

import subprocess

def execCmd(cmd=""):
    return subprocess.check_output(cmd, shell=True).decode().splitlines()

if __name__ == "__main__":
    for line in execCmd(r"dir d:\temp"):
        print(line)

For your specific example just use

cmd = "Merge -i file1.txt -i file2.txt -o out.txt" 

and the return value will be whatever lines of output would be written to the console if you ran it from the shell manually.

Use subprocess.run() https://python.land/operating-system/python-subprocess It receives a list, so it is easy to include parameters. Be sure to read about the shell=True option and decide whether it is necessary or not.
