What is an API?
An API is a way for different software components (or systems) to communicate with each other. Think of it like a menu at a restaurant — it lets you order (make requests) without knowing how the kitchen (server) prepares the food (data).
In Python, you often work with web APIs to fetch data from websites, cloud services, or apps. For example, you might use an API to get weather data or stock prices.
Why Learn APIs?
Data Access: Get data from services like Twitter, Spotify, or OpenWeatherMap.
Automation: Connect and control different apps.
Integration: Combine multiple systems or services (e.g., chatbots, web dashboards).
Practice with JSON: APIs usually return data in JSON format, a key skill in modern Python.
🐍 How to Use an API in Python?
The most popular library is requests. Here’s a simple example:
pythonCopyEditimport requests
# Make a GET request
response = requests.get("https://jsonplaceholder.typicode.com/posts")
# Check status code
if response.status_code == 200:
data = response.json() # Convert JSON to Python dictionary/list
print(data[0]) # Print the first item
else:
print("Error:", response.status_code)
