In Python, What Is The Method To Run A Program Or Invoke A System Command?

You can execute a program or call a system command in Python using the subprocess module. Here’s a basic example:

import subprocess

# Execute a program
subprocess.call(['program_name', 'arg1', 'arg2'])

# Call a system command
subprocess.call('system command', shell=True)

In the first example, subprocess.call() is used to execute a program by providing the program name and arguments as a list. Replace 'program_name', 'arg1', and 'arg2' with the actual program name and arguments.

In the second example, subprocess.call() is used to call a system command by providing the command as a string. Set shell=True to execute the command through the shell.

Note: The subprocess.call() function is a blocking function, meaning it will wait for the program or command execution to complete before proceeding with the next line of code. If you want to run the program or command asynchronously without blocking, you can use other functions available in the subprocess module such as subprocess.Popen().
