Python and other languages like Java, C#, and even C++ have had lambda functions added to their syntax, whereas languages like LISP or the ML family of languages, Haskell, OCaml, and F#, use lambdas as a core concept. Python lambdas are little, anonymous functions, subject to a more restrictive but more concise syntax than regular Python functions.

By the end of this course, you’ll know:

How Python lambdas came to be
How lambdas compare with regular function objects
How to write lambda functions
Which functions in the Python standard library leverage lambdas
When to use or avoid Python lambda functions

This course is mainly for intermediate to experienced Python programmers, but it is accessible to any curious minds with interest in programming. All the examples included in this tutorial have been tested with Python 3.7.

00:02 Hello, and welcome to this Real Python course where you’re going to learn how to use lambda functions. You’re going to find out what a lambda function is, where lambda functions are useful, create some first lambda functions of your own; see lambda functions in action with .sort(), filter(), map(), and reduce(); and learn how to test lambda functions.
