Lambda Overview

’Python Lambda A lambda function is a small anonymous function. A lambda function can take any number of arguments, but can only have one expression. Syntax lambda arguments : expression

Lambda Example 1

The expression is executed and the result is returned: Example1:=> A lambda function that adds 10 to the number passed in as an argument, and print the result:

x = lambda a : a + 10
print(x(5))

Lambda Example 2

Lambda functions can take any number of arguments: Example2:=> A lambda function that multiplies argument a with argument b and print the result

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

Lambda Example 3

A lambda function that sums argument a, b, and c and print the result:

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

Lambda Return as Function part1

The power of lambda is better shown when you use them as an anonymous function inside another function. Say you have a function definition that takes one argument, and that argument will be multiplied with an unknown number: Use that function definition to make a function that always doubles the number you send in

def myfunc(n):
  return lambda a : a * n
 
mydoubler = myfunc(2)  # lambda a : a * 2
print(mydoubler(11))
