Can you explain the principles of REST and how it differs from other API interaction methods?

REST (Representational State Transfer) is an architectural style for creating web services based on the use of standard HTTP methods (GET, POST, PUT, DELETE, etc.) for interacting with resources identified by URIs.

Main principles of REST:

• Client-server architecture: separation of responsibilities between client and server.
• Statelessness: each request from the client to the server must contain all the information needed.
• Caching: responses can be cached to improve performance.
• Uniform interface: standardized methods and formats for data exchange.

Differences from other API interaction methods:

• Unlike SOAP, REST is simpler and uses standard HTTP protocols without an additional messaging layer.
• REST does not require complex formats, typically using JSON or XML.
• REST is more flexible and scalable, suitable for web applications and mobile services.

Example of a REST API request in Python using requests:

import requests
response = requests.get('https://api.example.com/users/1')
if response.status_code == 200:
    user_data = response.json()
    print(user_data)
