# The lambda keyword in Python provides a
# shortcut for declaring small and
# anonymous functions:
add = lambda x, y: x + y
print(add(5, 3))
# Output
# 8
# You could declare the same add()
# function with the def keyword:
def add(x, y):
return x + y
print(add(5, 3))
# Output
# 8
# So what's the big fuss about?
# Lambdas are *function expressions*:
print((lambda x, y: x + y)(5, 3))
# Output
# 8
# • Lambda functions are single-expression
# functions that are not necessarily bound
# to a name (they can be anonymous).
# • Lambda functions can't use regular
# Python statements and always include an
# implicit `return` statement.

Facilitates functional programming - Lambda Expression facilitates functional programming and simplifies the development a lot.
To provide the implementation of the Java 8 Functional Interface.
Reduced Lines of Code - One of the clear benefits of using lambda expression is that the amount of code is reduced, we have already seen that how easily we can create instances of a functional interface using lambda expression rather than using an anonymous class.
Passing Behaviors into methods - Lambda Expressions enable you to encapsulate a single unit of behavior and pass it to other code.
For example, to other methods or constructors.

Step Functions is a serverless orchestration service that lets you easily coordinate multiple Lambda functions into flexible workflows that are easy to debug and change.
Step Functions will keep your Lambda functions free of additional logic by triggering and tracking each step of your application for you.
The Lambda runtime is fully managed by AWS. Once a function is uploaded and configured, Lambda is responsible for managing the resources required to run the code.
Developers are free from the traditional overhead of configuring and maintaining server instances.
Lambda will immediately scale to meet spikes in demand.
Lambda is cost-effective as you only pay for the computational resources used. This is, of course, true for other AWS compute services, but the cost model for Lambda is more granular than EC2 for example, with resources being charged per 100 milliseconds.
Lambdas event-driven model means you can integrate nicely with a range of AWS services, but still ensure loose coupling.
It’s very low cost. The first 1 million requests are free and you have to pay 0.20 per 1 million requests thereafter!!
