Status codes are standardized responses issued by a server in response to a client’s request made to the server. These codes help to understand whether a specific HTTP request has been successfully completed or if there was an error in processing the request. Status codes are divided into five categories:
1. 1xx (Informational): Request received, continuing process.
2. 2xx (Success): The action was successfully received, understood, and accepted.
3. 3xx (Redirection): Further action must be taken to complete the request.
4. 4xx (Client Error): The request contains bad syntax or cannot be fulfilled.
5. 5xx (Server Error): The server failed to fulfill a valid request.

Example about Status Code
Below is an example of how status codes might be implemented in a backend code snippet:
```python
from flask import Flask, jsonify
app = Flask(__name__)
@app.route('/resource', methods=['GET'])
def get_resource():
try:
Assume resource retrieval logic here
data = {"id": 1, "name": "Example Resource"}
return jsonify(data), 200 200 OK
except ResourceNotFound:
return jsonify({"error": "Resource not found"}), 404 404 Not Found
except Exception as e:
return jsonify({"error": "Internal Server Error"}), 500 500 Internal Server Error
if __name__ == '__main__':
app.run(debug=True)
```FAQs
