Function Composition

Concepts: pyFunctools

Function composition means combining simple functions to build complex operations. The output of one function becomes the input of the next. This is a core concept in functional programming. Data pipelines are perfect examples of composition. Raw data flows through a series of transformation functions: clean, validate, transform, aggregate, format. Each function does one thing well. Manual Composition The simplest form of composition is calling functions in sequence, where each function takes the previous result: Each function takes text and returns modified text. We chain them together to build the final result. The functions are reusable - you can combine them in different ways. Creating a Compose Function We can create a higher-order function that composes two functions into one new fun
