7. List Addition and Difference Map

Write a Python program to add two given lists and find the difference between them. Use the map() function.

Sample Solution:

Python Code :

# Define a function named addition_subtrction that performs addition and subtraction on two numbers
def addition_subtrction(x, y):
    return x + y, x - y

# Create two lists named 'nums1' and 'nums2' containing integer elements
nums1 = [6, 5, 3, 9]
nums2 = [0, 1, 7, 7]

# Print the original lists of numbers
print("Original lists:")
print(nums1)
print(nums2)

# Use the map function to apply the addition_subtrction function to pairs of corresponding elements
# from 'nums1' and 'nums2' and create a new list of tuples containing the results
result = map(addition_subtrction, nums1, nums2)

# Print a message indicating the operation to be performed
print("\nResult:")

# Print the result of the map operation as a list of tuples
print(list(result))

Sample Output:

Original lists:
[6, 5, 3, 9]
[0, 1, 7, 7]

Result:
[(6, 6), (6, 4), (10, -4), (16, 2)]
