Lambda function in Python
==============================
Lambda functions are simple functions that do not have a name assigned to them. They are usually created on the fly to perform small arithmetic or logical calculations and perform only a single expression on the provided arguments.
Python lambda function example
===========================
A simple example of a lambda function in Python is provided below:
var1 = lambda a: a*2
In the above example, we have created a simple lambda function that takes one argument "a" and multiplies this with "2" and returns the value to be saved to the "var1" variable.
How to execute a lambda function in Python
====================================
To execute a lambda function, we can simply call the variable with the required arguments. e.g: var1(10). This will pass the value 10 to the lambda function and the value gets multiplied by 2 and the result is sent back to var1.
When to use lambda function in Python
================================
Lambda functions are usually created and used in a Python program when we have to perform some simple and basic operations on a set of values. They are handy functions and does not have the complexity of a normal function that may have several expressions being evaluated inside the function body.
