  You can use lambda function in map() map() function applies a given function to all the itmes in a list and returns the result. Similar to filter(), simply pass the lambda function and the list (or any iterable, like tuple) as arguments. 12. You can use lambda function in reduce() as well

• When do we use map and Lambda in Python?

  Map function and Lambda expression in Python to replace characters. We want to replace a character a1 with a character a2 and a2 with a1. For example, and characters p and t, we want the end string to look like −. For this we can use map function and lambdas to make the replacement.

• What are Python lambda functions and how to use them?

  Use Python lambda expressions to create anonymous functions, which are the functions without names. A lambda expression accepts one or more arguments, contains an expression, and returns the result of that expression. Use lambda expressions to pass anonymous functions to a function and return a function from another function.

  A lambda function is a type of function that does not ha ve a name associated with it. Lambda functions are also known as anonymous functions for this reason.' In Python, lambda functions are created using the lambda keyword, and they are limited to expressions (not statements). Here is an e xample: Lecture 12: Lambda Functions

  lambda expression by constructing a corresponding English sentence: lambda x : f(g(x)) "A function that takes x and returns f(g(x))" The result of a lambda expression is called a lambda function. It has no intrinsic name (and so Python prints for the name), but otherwise behaves like any other
