Working with APIs and requests

What is API Requests in Python?

API Requests in Python means aPIs allow Python programs to communicate with web services and exchange data, usually in JSON format.

In real programs, this topic helps in fetching data from APIs. Learn the idea first, then type the program yourself and compare the output.

Why should you learn this?

• It is useful for fetching data from APIs.
• It connects with sending form data.
• It improves your ability to read, write and debug Python programs.

Important Terms

These terms are used directly in this lesson. Understand them before memorising the code.

Syntax / Basic Pattern

The simple pattern is: prepare data, apply the concept, then show the result.

import requests
url = "https://api.github.com"
response = requests.get(url, timeout=10)
print("Status:", response.status_code)
print("Content type:", response.headers.get("content-type"))

Complete Example Program

import requests

url = "https://api.github.com"
response = requests.get(url, timeout=10)

print("Status:", response.status_code)
print("Content type:", response.headers.get("content-type"))

Expected Output

Program Explanation

• import requests imports ready-made features from a module/library.
• url = "https://api.github.com" stores a value in url.
• response = requests.get(url, timeout=10) stores a value in response.
• print("Status:", response.status_code) displays information or calculated result on the screen.
• print("Content type:", response.headers.get("content-type")) displays information or calculated result on the screen.

Where will you use it?

• Fetching data from apis.
• Sending form data.
• Connecting python apps to web services.

Common Mistakes

• Making code complex when a simple function or class is enough.
• Not handling possible errors or edge cases.
• Mixing project dependencies instead of using a virtual environment.

Practice Tasks

1. Type the program in api-requests.py and run it.
2. Change input values or sample data and observe the new output.
3. Create one example related to fetching data from APIs.
4. Write 5 lines explaining the logic in your own words.

Summary

API Requests in Python is not a theory-only topic. You should be able to explain the meaning, write the example, run it successfully, and use it in a small practical program.
