Argparse optional boolean in python

Argparse optional boolean in python

Using argparse to handle optional boolean arguments in Python is quite straightforward. Here's an example of how you can define and parse optional boolean arguments using argparse:

import argparse def main(): parser = argparse.ArgumentParser(description='Optional Boolean Argument Example') # Add an optional boolean argument parser.add_argument('--enable-feature', action='store_true', help='Enable a feature') args = parser.parse_args() if args.enable_feature: print("Feature enabled!") else: print("Feature not enabled.") if __name__ == '__main__': main()

In this example, we're using the store_true action to create an optional boolean argument named --enable-feature. If the argument is provided when running the script, the value of args.enable_feature will be True; otherwise, it will be False.

You can run the script with the --enable-feature flag to enable the feature:

python script.py --enable-feature

Or without the flag to disable the feature:

python script.py

Remember that in boolean arguments created with store_true, you don't need to provide a value. The presence of the flag implies True, and the absence implies False.
