Working with APIs and requests

APIs और requests के साथ काम

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.

💡 At a Glance

Point	Details
Course Area	Advanced Python Professional concepts used to make code reusable, clean and project-ready.
Main Use	fetching data from APIs
Example File	`api-requests.py`
Practice Focus	Run, change values, and explain the output line by line.

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.

Term	Meaning
requests	requests is an important term in this topic.
GET	Request method used to fetch data from a server.
POST	Request method used to send data to a server.
status code	Number returned by a server to show request result, such as 200 or 404.
JSON response	Data returned from an API in JSON format.

Syntax / Basic Pattern

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

Basic Pattern

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

Python – api-requests.py

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

Status: 200 Content type: application/json; charset=utf-8

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

Type the program in api-requests.py and run it.
Change input values or sample data and observe the new output.
Create one example related to fetching data from APIs.
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.

Python API Requests क्या है?

Python API Requests ka matlab hai: APIs allow Python programs to communicate with web services and exchange data, usually in JSON format. Simple words me, ye topic practical Python programs likhne me direct use hota hai.

Is topic ko sirf definition ke liye nahi, balki fetching data from APIs jaise real examples ke liye practice karein.

यह क्यों सीखना जरूरी है?

Ye fetching data from APIs me kaam aata hai.
Ye sending form data se bhi connected hai.
Isse aap code ka output aur errors better samajh paate hain.

Important Terms

Term	Meaning
requests	requests is an important term in this topic.
GET	Request method used to fetch data from a server.
POST	Request method used to send data to a server.
status code	Number returned by a server to show request result, such as 200 or 404.
JSON response	Data returned from an API in JSON format.

Syntax / Basic Pattern

Basic idea: pehle data तैयार करें, phir Python logic apply करें, aur finally result display करें.

Basic Pattern

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

Python – api-requests.py

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

Status: 200 Content type: application/json; charset=utf-8

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.

Practical Uses

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

Program ko api-requests.py file me type karke run karein.
Values change karke output compare karein.
fetching data from APIs par ek छोटा example banayen.
Logic ko apne words me 5 lines me likhein.

सारांश

API Requests in Python ko tab complete maanenge jab aap iska meaning, example, output aur practical use clearly explain kar saken.
