Python: Calculate the average value of the numbers in a given tuple of tuples using lambda

Python Lambda: Exercise-44 with Solution

Write a Python program to calculate the average value of the numbers in a given tuple of tuples using lambda.

Sample Solution:

Python Code :

# Define a function 'average_tuple' that calculates the average of elements in a tuple of tuples
def average_tuple(nums):
    # Use 'zip(*nums)' to unpack the tuples in 'nums' and then apply 'map' with a lambda to calculate the averages
    # For each position (index) in the unpacked tuples, calculate the average of elements at that position across tuples
    # Convert the averages into a tuple
    result = tuple(map(lambda x: sum(x) / float(len(x)), zip(*nums)))
    
    # Return the tuple of average values
    return result

# Create a tuple of tuples 'nums' containing integer values
nums = ((10, 10, 10), (30, 45, 56), (81, 80, 39), (1, 2, 3))

# Print the original tuple 'nums' and the average value of numbers in the tuple of tuples using 'average_tuple' function
print("Original Tuple:")
print(nums)
print("\nAverage value of the numbers of the said tuple of tuples:\n", average_tuple(nums))

# Create another tuple of tuples 'nums' containing integer values including negative numbers
nums = ((1, 1, -5), (30, -15, 56), (81, -60, -39), (-10, 2, 3))

# Print the original tuple 'nums' and the average value of numbers in the tuple of tuples using 'average_tuple' function
print("\nOriginal Tuple:")
print(nums)
print("\nAverage value of the numbers of the said tuple of tuples:\n", average_tuple(nums)) 

Sample Output:

Original Tuple: 
((10, 10, 10), (30, 45, 56), (81, 80, 39), (1, 2, 3))

Average value of the numbers of the said tuple of tuples:
 (30.5, 34.25, 27.0)

Original Tuple: 
((1, 1, -5), (30, -15, 56), (81, -60, -39), (-10, 2, 3))

Average value of the numbers of the said tuple of tuples:
 (25.5, -18.0, 3.75)
