Python Argparse Tutorial – Argparse HowTo

Posted on October 22, 2025October 28, 2025 by Marco Antonio Carcano

The Python Argparse Tutorial - Argparse HowTo post provides a practical example of how to parse command line parameters and options using the argparse module.

Knowing how to add command line paramenters and options to Python scripts is a must-have skill, since it enables them to better adapt to customers' needs, allowing them to enable or disable specific script features, or providing information on the operational environment structure, such as specific directory paths different from the default ones.

As a professional, you are supposed to always add command line arguments support to your scripts, so to make them always fit to the user-specific scenarios.

JINJA2 is a powerful yet easy to use templating engine that enables easily generating documents on the fly blending one or more objects with a template.

Since the syntax is heavily inspired by Django and Python, JINJA2 is not only commonly used inside Python scripts: it is very often exploited by Ansible, for example when generating configuration files on the fly.

In "JINJA2 With Python Tutorial JINJA Ansible Howto" post we will learn all the must know about JINJA2, and experiment with it by writing a real-life JINJA2 template file, rendering it by merging it with a JSON document using a custom Python script and an Ansible playbook.

This is the last post of the trilogy dedicated to how to set up a well structured Python project, developed with professional style, suitable to be used within the context of a Continuous Integration toolchain. This time we focus on how to package all we have done so far as RPM packages, showing how to break down everything into subpackages that also perform post installation tasks.
If you haven't read the previous two posts, you must do it right now since they are requisite to understand this post. In addition to that this post relies onto objects that are being created in the previous posts.

Read them in the following order:

The operating environment used in this post is Red Hat Enterprise Linux 8 or CentOS 8 - using a different environment may lead to having to adapt or even change things.
