Python Lambda Functions

Chapter: Python Last Updated: 11-11-2021 18:14:12 UTC

Program:

            /* ............... START ............... */
                
x = lambda a: a + 10
print(x(5))

/*
15
*/

x = lambda a, b: a * b
print(x(5, 6))
/*
30
*/

x = lambda a, b, c: a + b + c
print(x(5, 6, 2))
/*
13
*/



def myfunc(n):
  return lambda a : a * n

mydoubler = myfunc(2)

print(mydoubler(11))

/*
22
*/


def myfunc(n):
  return lambda a : a * n

mytripler = myfunc(3)

print(mytripler(11))

/*
33
*/

                /* ............... END ............... */
        

Notes:

  • Lambda function in python is a small anonymous function. It can take any number of arguments, but can have only one expression.
  • Mostly lambda function in python is used as anonymous function inside another function. (This is main powerful feature of lambda).
  • You can see from first program it will take one variable as arguments and it will be multiplied by a number (Syntax : x = lambda a: a + 10)
  • Second program will use two arguments for processing (Syntax : x = lambda a, b: a * b), so when are calling user should call with two arguments.
  • In third program it taking three arguments and result will according to the expression. Python lambda can take any number of arguments.
  • In the last two program you can see that lambda is used in functions, so it will return the value of lambda expression mentioned in function content.
