Lambda Functions

Lambda functions are small anonymous functions defined with the lambda keyword.

Syntax

The syntax of a lambda function is: lambda arguments: expression.

square = lambda x: x ** 2
print(square(5))  # Output: 25

Using Lambda with map

You can use lambda functions with functions like map.

numbers = [1, 2, 3, 4]
squared_numbers = list(map(lambda x: x ** 2, numbers))
print(squared_numbers)  # Output: [1, 4, 9, 16]
