In Python, a lambda function is an anonymous function defined using the lambda keyword. Unlike regular functions that use def , lambda functions are typically written in a single line for simplicity and convenience. lambda x: x + 1 This defines a function that takes an input x and returns x + 1 . For example: print((lambda x: x + 1)(5)) # Output: 6 2. Why Was the Lambda Function Introduced? Lambda functions stem from functional programming concepts. Although Python is primarily an object-oriented language, it also supports functional paradigms. In this model, functions are first-class citizens, meaning they can be passed as arguments, returned from other functions, or assigned to variables.
