As we already know that def keyword is used to define the normal functions and the . Not true, in the example the lambda definition is evaluated . An intro to functional programming in Python covering Lambda , Map , Filter and Reduce functions. A simple introduction to Pythons basic functions covering Lambda , Map , Filter and Reduce. In this short Python tutorial I show the Map function by an example, in which I add numbers of two lists. Einführung in den Lambda -Operator und die Funktionen map , filter und reduce. Python lambdas are little, anonymous functions, subject to a more.

The lambda is an anonymous function that is nameless and generally used with higher order functions like map , filter etc. You have to generate a list of the first .
