What is the return type of a lambda function?

A lambda function in Python is designed to be a small anonymous function that can take any number of arguments but has a single expression. The return type of a lambda function is not limited to a specific data type; rather, it can return any data type, including integers, strings, lists, tuples, dictionaries, and even other functions or objects. This flexibility allows lambda functions to be used in a variety of contexts, such as in higher-order functions like map(), filter(), or sorted(), where the return values can be dynamically different depending on the input and the expression defined within the lambda itself.

This dynamic return type is a key feature that distinguishes lambda functions, making them versatile tools in functional programming within Python.
