## Overview

This repository is a collection of independent practice files, not one integrated application. The sampled files show a username-validation function, a small HTTP server, and an employee-date CSV; the README describes course-separated practice files but does not explain the CSV’s intended use. The server handles GET requests with a greeting and host information. Other course contents are not represented as runtime components because their behavior is not shown.

Main entry points: [`Course5/Lab3/hello_cloud.py`](https://github.com/ramaromadhon123/it-cert-automation-practice/blob/master/Course5/Lab3/hello_cloud.py) (GET handler), [`Course3/Lab4/validations.py`](https://github.com/ramaromadhon123/it-cert-automation-practice/blob/master/Course3/Lab4/validations.py) (Username validation)
