Important concepts

• Command-line arguments: These are options or parameters that can be passed to a script when it is run from the command-line. They allow users to modify the behavior of the script and can include things like file paths, settings, and flags.
• Parsing: This refers to the process of analyzing and interpreting the command-line arguments passed to a script. It involves breaking down the arguments into individual components and extracting the relevant information.
• Boolean values: These are data types that can have one of two possible values: True or False. They are often used to represent yes/no or on/off options in command-line scripts.
• argparse module: This is a built-in Python library that provides a convenient way to parse command-line arguments. It allows users to specify options and arguments in a user-friendly way and also provides features like automatic help messages and error handling.
• add_argument() method: This is a method provided by the argparse module that allows users to add command-line arguments to a script. It takes various parameters, such as the name of the argument, its type, and whether or not it is required.
• parse_args() method: This method is used to parse the command-line arguments passed to a script. It takes the arguments provided to the script and returns an object containing the values of the arguments.

Command-line arguments are a powerful feature of many programming languages, including Python. They allow developers to specify options or parameters when running a script, making it more flexible and customizable. However, the process of parsing these arguments can be a tedious and error-prone task if done manually. The ‘argparse’ module in Python provides an easy and elegant way to parse command-line arguments, making it a popular choice among developers.

The argparse is a built-in Python library for parsing command-line arguments. As mentioned above it allows users to certain options and arguments for a script in a more organized and user-friendly way.

One common type of argument that you may want to accept is a boolean value, which can be either True or False. In this tutorial, we’ll show you how to use ‘argparse’ to parse boolean values.

For the process of parsing boolean values with argparse, you can use the add_argument() method and set the action parameter to “store_true” or “store_false“. The store_true option has a default value of False. Whereas, store_false has a default value of True.
