Python Mastery

Python is the backbone of infrastructure automation. Master it from basics to building production CLIs like netapi.

Why Python Matters

Domain	Applications
Infrastructure Automation	netapi, Ansible, Terraform providers, cloud SDKs
API Development	FastAPI, Flask, REST clients, webhook handlers
CLI Tools	Click, Typer, Rich for professional interfaces
Data Processing	pandas, JSON/YAML parsing, log analysis
Security	cryptography, certificate handling, secrets management
Testing	pytest, mocking, integration testing

Quick Reference

Running Python

# REPL
python3

# Run script
python3 script.py

# Run module
python3 -m module_name

# With uv (preferred)
uv run python script.py
uv run pytest

Project Setup

# Create project with uv
uv init my-project
cd my-project

# Add dependencies
uv add click rich httpx

# Add dev dependencies
uv add --dev pytest pytest-cov

# Run
uv run python -m my_project
