Python: Create a lambda function that adds 15 to a given number passed in as an argument
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.
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.
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).
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.
