How Do I Parse Command Line Arguments in Python?

Command Line Argument Parsing in Python

In Python, the sys.argv list holds all arguments provided to a script upon execution. To retrieve and process these arguments, utilize the following steps:

1. Import the sys Module:

import sys

2. Print Command Line Arguments:

Print all provided arguments to the console:

print("\n".join(sys.argv))

3. Access Specific Arguments:

To access specific arguments, use their positional index in sys.argv:

print(sys.argv[0])  # Script name
print(sys.argv[1:])  # All arguments except the script name

For example, if you execute a script with the following command:

python script.py arg1 arg2 arg3

sys.argv would be:

['script.py', 'arg1', 'arg2', 'arg3']
