python script optional arguments

in python, command-line scripts often require input from the user. to make scripts more versatile, we can use optional arguments. optional arguments allow users to provide additional inputs to the script when running it from the command line. in this tutorial, we'll explore how to implement optional arguments in a python script with code examples.
the argparse module in python makes it easy to parse command-line arguments. it provides a convenient way to define, parse, and validate optional and positional arguments.
instantiate an argumentparser object, which will handle the parsing of command-line arguments.
the description parameter is optional and can be used to provide a brief explanation of what your script does.
add optional arguments using the add_argument method. specify the argument name (short and long forms), data type, default value, and help message.
in the above example:
parse the command-line arguments using the parse_args method.
now, the args variable contains the values of the parsed arguments.
access the parsed arguments in your script and use them as needed.
run your script from the command line and provide optional arguments as needed.
implementing optional arguments in python scripts using the argparse module enhances the flexibility and usability of your command-line programs. users can customize the behavior of the script by providing optional arguments based on their specific needs.
