APIs & The Web

Module 4: Connecting your Python logic to real-world data across the internet.

SYSTEM: HTTP_PROTOCOL

31 // The Request/Response Cycle

The internet is just a conversation. Your Python code (The Client) asks for something, and a Server sends it back.

AI Insight: - GET: Asking for data (e.g., Reading a tweet). - POST: Sending data (e.g., Submitting a password). - Status 200: Success! - Status 404: Not Found.

SYSTEM: REQUESTS_LIB

32 // The Requests Library

Python's most powerful tool for talking to the web. We use it to pull data from any URL.

import requests response = requests.get("https://api.github.com/users/EazeAi666") data = response.json() print(f"Followers: {data['followers']}")

SYSTEM: WEB_DATA

33-39 // Parsing & Scoping

Lesson 33: JSON Mastery — Navigating complex nested dictionaries from APIs.

Lesson 34: API Keys — Learning how to hide your secret passwords using Environment Variables.

Lesson 35: Rate Limiting — How to avoid getting banned by servers for asking for too much data too fast.

Lesson 36-39: Introduction to Flask — Briefly touching on how to build your OWN server using Python.


CAPSTONE_PROJECT_04

40 // Project: Real-Time Weather Agent

Build a tool that asks the user for a city (e.g., "Lagos"), connects to a Weather API, and prints the current temperature and humidity.

🌍 MARKET APPLICATION Agriculture and Logistics companies in Nigeria use these exact API systems to track weather patterns and optimize delivery routes. You are now building tools that solve regional problems.
