An ultra basic Python CLI example with no frameworks or dependencies. In just a few minutes you can have all you need to create a super simple, single-file Python CLI tool without any external dependencies or frameworks.
Build a very simple command line tool with Python without using external dependencies or frameworks. In this video you'll see how with just a few lines of Python you can transform a file into a script with a help menu.
Although you can create more powerful command-line tools with other frameworks like argparse or external libraries like Click, you can still implement a quick script without them that includes a help menu
Because you need something very quick, easy to run, ideally with a single argument, and most of the time for other systems to use. No need for fancy help menus (although you can add those), and hopefully with a single task to do.
Now that you know how to do this minimal Python CLI tool, you can try out other frameworks like Python's argparse module or the Click framework. I have examples and guides for argparse CLI tools and for using the Click framework.
