Argparse
The argparse module allows you to create user-friendly command-line interfaces, making your scripts reusable, configurable, and easy to document.
Argparse
argparse is a built-in Python module that makes it easy to write scripts that accept command-line arguments. This lets users run your script with custom inputs without modifying the code.
Example
pythonCopyEditimport argparse parser = argparse.ArgumentParser(description="Greet a user") parser.add_argument("name", help="The name of the user") args = parser.parse_args() print(f"Hello, {args.name}!")
Usage:
bashCopyEditpython greet.py Alice # Output: Hello, Alice!
Argument Types and Defaults
pythonCopyEditparser.add_argument("--times", type=int, default=1, help="How many times to repeat")
Creating Help Text
Run your script with --help to generate documentation:
bashCopyEditpython greet.py --help
Output:
lessCopyEditusage: greet.py [-h] [--uppercase] [--times TIMES] name
Conclusion
With argparse, your scripts become more flexible, user-friendly, and ready for automation pipelines. It’s a key tool for writing robust command-line utilities in Python.
