How do I use command line arguments in Python?

You can use the sys module to access command line arguments in Python. Import it and use sys.argv.

Can you give me an example of how to do that?

Sure! Here's a simple example:

import sys

# Print all command line arguments
print('Arguments:', sys.argv)

What if I want to convert those arguments to integers?

You can use a list comprehension to convert them:

numbers = [int(arg) for arg in sys.argv[1:]]  # Skip the script name

Is there a way to handle errors if the conversion fails?

Yes, you can use a try-except block to catch conversion errors:

try:
    numbers = [int(arg) for arg in sys.argv[1:]]
except ValueError:
    print('Please provide valid integers.')
