What are some examples of Lambda functions?

Lambda functions are small, anonymous functions defined with the lambda keyword. They can be used for various tasks. For example, you can use a Lambda function to sort a list of numbers or to filter items in a collection.

Can you give me a specific example of a Lambda function in Python?

Sure! Here's a simple example in Python: square = lambda x: x * x. You can use it like this: print(square(5)), which will output 25.

What about using Lambda functions with higher-order functions?

Absolutely! Higher-order functions like map, filter, and reduce can take Lambda functions as arguments. For instance, list(map(lambda x: x * 2, [1, 2, 3])) will return [2, 4, 6].

Are there any limitations to using Lambda functions?

Yes, Lambda functions are limited to a single expression and cannot contain statements or annotations. They are best used for simple operations.
