Question

How to find the product of elements between tuples in a dictionary by index with Python

Answer 1

def productTuple(tpl):
    result = 1
    
    print(tpl)
    
    for item in tpl:
        result *= item
      
    return result

# Create a dictionary with tuples as values
dict = {'a': (1, 2, 3), 'b': (4, 5, 6), 'c': (7, 8, 9)}

print("Dictionary: " + str(dict))

# Calculate the product between the tuples elements
result = tuple(productTuple(element) for element in zip(*dict.values()))

print("Result: " + str(result))



'''
run:

Dictionary: {'a': (1, 2, 3), 'b': (4, 5, 6), 'c': (7, 8, 9)}
(1, 4, 7)
(2, 5, 8)
(3, 6, 9)
Result: (28, 80, 162)

import operator
from functools import reduce

def productTuple(dict):
   return tuple(map(lambda *args: reduce(operator.mul, args), *dict.values()))

# Create a dictionary with tuples as values
dict = {'a': (1, 2, 3), 'b': (4, 5, 6), 'c': (7, 8, 9)}
print("Dictionary: " + str(dict))

result = productTuple(dict)
print("Result: " + str(result))
