In this article, five important functions are explained in detail with code. These functions are simple yet the most powerful function in Python. Python has many libraries and built-in functions. Understanding these functions and using them properly helps with efficient programming.

1. Lambda Function:

One of the most powerful functions in Python also known as the anonymous function. It is known as anonymous because we can instantiate and declare a function without a name. If you have a single operation to be executed, the lambda function is extremely useful instead of declaring a traditional function. Lambda is similar to the function, except it can only return only one expression.

A Python program to find the value for (a+b)^2 using lambda

answer = lambda a, b: a**2 + b**2 + 2*(a+b)
print(answer(3, 6))

Note:

• The syntax for lambda function is lambda arguments: expression
• Lambda doesn’t require a name and, returns statement lambda keyword is used.
• Also, notice that the function is called a reference variable called the answer.
• You can also use lambda functions inside…
