Command line arguments are a powerful way to interact with Python scripts, allowing users to provide input parameters when executing a script. The argparse module in Python provides a convenient way to parse command line arguments and handle user input effectively. In this tutorial, we'll explore the basics of using argparse with practical examples.
Import argparse module:
To begin, import the argparse module into your Python script.
Create ArgumentParser object:
Initialize an ArgumentParser object, which will hold all the information necessary to parse the command-line arguments.
Add arguments using add_argument method:
Specify the arguments that your script accepts using the add_argument method. Define the argument names, type, help messages, and other relevant information.
Parse the command line arguments:
Parse the provided command line arguments using the parse_args method.
The args object now contains the values of the parsed arguments.
Accessing values:
Access the values of the parsed arguments using dot notation on the args object.
Putting it all together, here's a complete example:
Save the script, for example, as script.py. To run it from the command line:
Adjust the arguments according to your script's requirements.
Congratulations! You've created a Python script that accepts command line arguments using the argparse module. This approach enhances the usability and versatility of your scripts, making them more user-friendly.
