![]() In the above program, lambda x: x * 2 is the lambda function. # Program to show the use of lambda functions double = lambda x: x * 2 print(double(5)) This is the simplicity of lambda functions.ġ. We can also put a lambda definition anywhere a function is expected, and we don’t have to assign it to a variable at all. Using Lambda : Lambda definition does not include a “return” statement, it always contains an expression which is returned.After execution, we also needed to return the result from where the function was called using the return keyword. But, while using def, we needed to define a function with a name cube and needed to pass a value to it. Without using Lambda : Here, both of them returns the cube of a given number. ![]() def square(y): return y*y g = lambda x: x*x print(g(7)) print(cube(5)) #PYTHON LAMBDA CODE#Variable(arguments) difference between a normal def defined function and lambda function # Python code to illustrate cube of a number # showing difference between def() and lambda(). we can assign it to variables and use as with objects.ie, ![]() ie, can pass any number of arguments, but can only perform one operation on themįunctions are objects in python, Lambda functions can be used wherever function objects are required. They are syntactically restricted to a single expression. (anonymous here just means nameless functions) syntax: Lambda functions are used along with built-in functions like filter(), map() etc. In Python, we generally use it as an argument to a higher-order function (a function that takes in other functions as arguments). Like nested function definitions, lambda functions can reference variables from the containing scope. Semantically, they are just syntactic sugar for a normal function definition. Lambda expressions in Python and other programming languages have their roots in lambda calculus, a model of computation invented by Alonzo Church ![]()
