Functions can be defined with “def” and lambdas from "summary" of Fluent Python by Luciano Ramalho
The concept of defining functions with “def” and lambdas is fundamental to Python programming. The “def” keyword is used to create named functions, which are reusable blocks of code that perform a specific task. When you define a function using “def”, you give it a name and specify the parameters it takes. Inside the function body, you write the code that implements the desired functionality. This code is executed whenever the function is called with the specified arguments. In contrast, lambdas are anonymous functions that are defined using the “lambda” keyword. Lambdas are useful for creating small, one-off functions without having to formally define them with a name. The syntax of a lambda function is concise, consisting of the “lambda” keyword followed by a list of parameters, a colon, and a single expression that is eval...
