Python Lambda Function with Two Arguments

Lambda Function with Two Arguments in Python

To define a Lambda Function with two argument in Python, specify the two parameters after lambda keyword.

For example, the following is a lambda function that takes two arguments and returns their product.

lambda x,y: x*y

Please note that the parameters are separated by comma , symbol. Also, the parameters and the function body are separated by colon : symbol.

Examples

1. Find product of two numbers using lambda function

In this example, we shall define a lambda function that takes two arguments: x, y; and returns their product.

Python Program

product = lambda x,y: x*y

num1 = 5
num2 = 3
result = product(num1,num2)
print(f"Product of {num1} and {num2} is {result}.")

Output

Product of 5 and 3 is 15.

2. Lambda function to check if two given numbers are even

In this example, we shall define a lambda function that takes two arguments: x, y; and returns true only if both the arguments are even numbers, else it returns false.

Python Program

bothEven = lambda x,y: x % 2 == 0 and y % 2 == 0

num1 = 8
num2 = 14

if bothEven(num1,num2):
    print("Both the numbers are even.")
else:
    print("Both the numbers are not even.")

Output

Both the numbers are even.

Summary

In this tutorial of Python Lambda Function, we learned how to define a lambda function with two arguments, with the help of example programs.
