In Python, the main function is a common convention used in scripts and programs. It serves as the entry point for the execution of the script. When writing more complex programs, you may need to handle command-line arguments to make your script more versatile. This tutorial will guide you through the basics of handling arguments in the main function using the argparse module.
The argparse module simplifies the process of parsing command-line arguments. Import it at the beginning of your script.
Instantiate an ArgumentParser object to define the command-line arguments your script will accept.
In the example above, we've defined a positional argument (positional_argument) and an optional argument (optional_argument). The type parameter specifies the data type of the argument, and help provides a description for the argument. The default parameter sets a default value for optional arguments.
Adjust your main function to use the parsed arguments.
Save your script and run it from the command line, providing the required arguments.
Replace your_script.py with the actual name of your Python script and adjust the provided values accordingly.
Now you have a script that can accept command-line arguments. This makes your Python program more flexible and user-friendly, allowing users to customize its behavior without modifying the script itself.
