1. Lambda Add & Multiply

Write a Python program to create a lambda function that adds 15 to a given number passed in as an argument, also create a lambda function that multiplies argument x with argument y and prints the result.

Sample Solution:

Python Code :

# Define a lambda function 'r' that takes a single argument 'a' and returns 'a + 15'
r = lambda a: a + 15

# Print the result of calling the lambda function 'r' with argument 10
print(r(10))

# Reassign 'r' to a new lambda function that takes two arguments 'x' and 'y' and returns their product
r = lambda x, y: x * y

# Print the result of calling the updated lambda function 'r' with arguments 12 and 4
print(r(12, 4))

Sample Output:

25
48

Explanation:

In the exercise above -

Lambda Function Creation:

r = lambda a: a + 15

This line creates a lambda function named r.
The lambda function takes a single argument a and returns a + 15.
This lambda function adds 15 to the arguments passed to it.

Lambda Function Invocation:

print(r(10))

The code calls the lambda function r with the argument 10.
It prints the result of invoking the lambda function with 10, which evaluates to 10 + 15 = 25.

Reassignment of r to a New Lambda Function:

r = lambda x, y: x * y

This line reassigns the variable r to a new lambda function.
The new lambda function takes two arguments x and y.
It returns the product of x and y (x * y).

Lambda Function Invocation with Multiple Arguments (Line 7):

print(r(12, 4))

This code calls the updated lambda function r with arguments 12 and 4.
It prints the result of invoking the lambda function with 12 and 4, which evaluates to 12 * 4 = 48.
