2-Minute Guide: argparse — CLI Arguments for Python Scripts

When writing Python scripts, it's often necessary to pass command-line arguments to customize the script's behavior. The argparse library provides a powerful and flexible way to handle CLI arguments. In this guide, we'll explore a minimal example of using argparse to parse command-line arguments.

Minimal Example

Here's a simple example of using argparse to parse --name and --count flags:

python
import argparse

parser = argparse.ArgumentParser()
parser.add_argument('--name', help='Your name')
parser.add_argument('--count', type=int, help='Number of times to greet')

args = parser.parse_args
