Python Developer Roadmap (Dev Zero)¶
This roadmap provides a structured path for system administrators and developers to learn Python, focusing on practical automation and system integration.
Python is the "second best language for everything." While it may not be the fastest at runtime or as expressive as Perl for one-liners, its readability and vast library ecosystem make it the industry standard for system automation, data engineering, web development, and security tooling.
Guides¶
Setting up your environment, virtual environments, and basic syntax for sysadmins.
Lists, dictionaries, and controlling flow with loops and conditionals.
Reading/writing files, parsing JSON, and making HTTP requests.
Using os, subprocess, and shutil to replace shell scripts with Python.
Writing tests with pytest and managing dependencies with pip and poetry.
Classes, inheritance, dataclasses, protocols, and practical OOP patterns.
Closures, decorators, generators, the import system, and package management.
