Advanced Python: Using APIs (Internet Data)

Goal

• Fetch data from the internet
• Understand JSON

Step 1: Understanding APIs

API = interface that provides you with data from the internet.

Examples:

• Weather data
• Bitcoin price
• News

Step 2: requests Module

import requests

response = requests.get("https://api.coindesk.com/v1/bpi/currentprice.json")
data = response.json()

print(data)

Explanation:

• requests.get() → fetches data from the internet
• .json() → converts the response into a Python dictionary

Step 3: Reading Data

print(data["bpi"]["USD"]["rate"])

Explanation:

• Accesses the Bitcoin price in USD
• JSON works like a nested dictionary

Task

• Fetch current data (e.g., weather or prices)
• Display only the important information
