They are often used for short-lived operations and are commonly employed with functions like map(), filter(), and sorted(). Here is an example of a lambda function in Python: # Lambda Function to print square of numberAdder = lambda x:x*x# Calling the function:Adder(3) Output:9 ...
Themap()function takes in an iterable and a function and applies the function to each item in the iterable, as shown: Let’s create anumslist and use themap()function to create a new list that contains the square of each number in thenumslist. Notice the use of lambda function to def...

In this tutorial, we'll demonstrate how to effectively use decorators in Python functions. Functions as First-Class Objects Functions in Python are first class citizens. This means that they support operations such as being passed as an argument, returned from a function, modified, and assigned ...
The most basic for loop use in Python is to iterate over a range, essentially creating a loop that will only iterate for a set number of times. While “range” is not strictly part of the syntax for a for loop, it is really a built-in Python function that returns a sequence for a...
