What are some examples of Python Lambda functions in web development?

Python Lambda functions are small anonymous functions defined with the lambda keyword. In web development, they can be used for various tasks such as handling API requests, processing data, or even creating simple web applications.

Can you give me a specific example of how to use a Lambda function in a web app?

Sure! For instance, you can use a Lambda function to handle a POST request in a Flask web application. Here's a simple example:

from flask import Flask, request

app = Flask(__name__)

@app.route('/add', methods=['POST'])
def add():
    data = request.json
    result = (lambda x, y: x + y)(data['a'], data['b'])
    return {'result': result}

This Lambda function takes two numbers from the JSON request and returns their sum.

What are the benefits of using Lambda functions in web development?

The benefits include reduced code complexity, improved readability, and the ability to create quick, throwaway functions without formally defining them. They also help in writing concise code for simple operations.

Are there any limitations to using Lambda functions?

Yes, Lambda functions are limited to a single expression and cannot contain multiple statements or annotations. They also may not be suitable for complex operations or when readability is a concern.
