Building Command Line Interfaces With argparse

One of the strengths of Python is that it comes with batteries included: it has a rich and versatile standard library that makes it one of the best programming languages for writing scripts for the command line. But, if you write scripts for the command line, then you also need to provide a good command line interface, which you can create with the Python argparse library.

In this video course, you’ll learn:

  • What the Python argparse library is, and why it’s important to use it if you need to write command line scripts in Python
  • How to use the Python argparse library to quickly create a simple CLI in Python
  • What the advanced usage of the Python argparse library is

This video course is for early intermediate Pythonistas who probably write scripts in Python for their everyday work but have never implemented a command line interface for their scripts.

If that sounds like you, and you’re used to setting variable values at the beginning of your scripts or manually parsing the sys.argv system list instead of using a more robust CLI development tool, then this video course is for you.
