What are the differences between the subprocess and os modules in Python?

The subprocess module is used for spawning new processes, connecting to their input/output/error pipes, and obtaining their return codes. In contrast, the os module provides a way to interact with the operating system, including file and directory manipulation.

Can you give me an example of how to use subprocess?

Sure! Here's a simple example:

import subprocess
result = subprocess.run(['ls', '-l'], capture_output=True, text=True)
print(result.stdout)
``` This runs the 'ls -l' command and captures the output.

What about using the os module for the same task?

You can use the os module like this:

import os
output = os.popen('ls -l').read()
print(output)
``` This also lists the files in the current directory.

Which one is better to use?

It depends on your needs. Use subprocess for more complex interactions with processes, and os for simpler file operations.
