How can one view CMD messages while executing an executable through CMD using Python?

edit

One way to view CMD messages while executing an executable through CMD using Python is to use the subprocess module. Here's an example code snippet:

import subprocess

cmd = 'my_executable.exe arg1 arg2'
# Replace 'my_executable.exe' and 'arg1 arg2' with the actual executable and arguments

p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

# Read the output line by line as it's generated
while True:
    line = p.stdout.readline()
    if not line:
        break
    print(line.strip().decode())

This code snippet creates a new process using the Popen function from the subprocess module, passing in the command and arguments as a string, and redirecting both stdout and stderr to a pipe. Then it reads the output line by line as it's generated using a loop, printing each line to the console. This way, you can see the CMD messages in real-time as they're generated by the executable.
