Title: Python argparse Tutorial: Handling Boolean Flags
Introduction:
Argparse is a powerful module in Python that allows you to parse command-line arguments in a convenient and structured way. In this tutorial, we will explore how to handle boolean flags using argparse, allowing you to control the behavior of your Python scripts with command-line options.
Step 1: Import argparse
The first step is to import the argparse module into your Python script.
Step 2: Create an ArgumentParser object
Next, create an ArgumentParser object to define and manage the command-line arguments.
Step 3: Add boolean flags
Add boolean flags to the ArgumentParser object using the add_argument method. For boolean flags, use the action='store_true' argument.
In the above example, we've added two boolean flags: --verbose and --debug. The action='store_true' argument tells argparse to set the value to True if the flag is present.
Step 4: Parse the command-line arguments
Parse the command-line arguments using the parse_args() method of the ArgumentParser object.
Step 5: Use the boolean flags in your script
Now you can use the values of the boolean flags in your script based on the user's command-line input.
Complete Example:
Here's a complete example of a Python script using argparse with boolean flags:
Usage:
Run the script from the command line and experiment with the boolean flags:
Conclusion:
Argparse simplifies the process of handling command-line arguments in your Python scripts. By following this tutorial, you can easily implement boolean flags to control the behavior of your scripts based on user input.
