What is Defining Functions?
User-defined functions are created with the def keyword and encapsulate reusable logic. A function takes parameters, executes a body, and returns a value with return. Writing well-scoped functions makes analysis code modular, testable, and easier to apply across a dataset using Pandas' apply() method.
