What is a lambda function in Python?

Problem Statement

Explanation

A lambda function is an anonymous, one-line function defined using the keyword lambda. It can take any number of inputs but only one expression, which is automatically returned. They are used when a short function is needed temporarily, for example as a key in sorting or inside functions like map and filter. Though concise, excessive use of lambda can hurt readability compared to normal function definitions.
