Python optparse and file mask

in this tutorial, we'll explore how to use python's optparse module to create a command-line tool that can process files using file masks. we'll start by introducing the optparse module, then walk through the steps of creating a python script that accepts file masks as input and performs actions on matching files.
optparse is a python module that provides a convenient way to parse command-line arguments and options. it allows you to define the options and arguments your script accepts and automatically generates help messages and error handling.
to follow along with this tutorial, you should have:
first, you need to import the optparse module into your python script:
next, you'll create a function to parse the command-line arguments and options. here's a basic structure for this function:
in this function:
let's define a common option: -d or --directory, which specifies the directory where you want to search for files. add the following code within the parse_command_line function:
you can define additional options based on your requirements.
now, let's write code to process file masks. we'll use the glob module to match files based on the provided file mask. here's an example of how to do this within your script:
in this code:
now, you can run your script from the command line:
in this tutorial, you've learned how to use the optparse module in python to create a command-line tool that can process files using file masks. you can extend this script by adding more options and custom file-processing logic based on your specific needs.
