Certainly! Passing arguments to a Python script is a common and useful practice, especially when you want to make your script more versatile and configurable. In this tutorial, I'll guide you through the process of passing arguments to a Python script using the argparse module, which is a standard library module for parsing command-line arguments.
The argparse module simplifies the process of parsing command-line arguments. Start by importing it in your Python script.
Create an ArgumentParser object to handle the command-line arguments.
The description parameter is optional but can be used to provide a brief explanation of what your script does.
Use the add_argument method to define the arguments your script will accept. Specify the name of the argument and its type, and add an optional help message.
In this example, we define three arguments:
Parse the command-line arguments using the parse_args method.
This will return an object containing the values of the parsed arguments.
Now, you can use the values of the parsed arguments in your script.
You can then use these variables as needed in your script.
Here's a complete example script that incorporates the steps above:
Save the script and run it from the command line. For example:
This would run your script with input.txt as the input file, output.txt as the output file, and verbose mode enabled.
