PR Description

Added a comprehensive guide on lambda functions in Python, covering their definition, syntax, differences from regular functions, and practical use cases. The post includes examples illustrating sorting, filtering, mapping, event handling, callback functions, and anonymous functions in higher-order functions. Concluded with a summary highlighting the benefits and versatility of lambda functions in Python programming.

Along with creating lambda-function.md, I've also updated index.md of advanced-python
