Python: Create the running product of an iterable
Python Itertools: Exercise-2 with Solution
Write a Python program that generates the running product of elements in an iterable.
Sample Solution:
Python Code:
from itertools import accumulate
import operator
def running_product(it):
return accumulate(it,operator.mul)
#List
result = running_product([1,2,3,4,5,6,7])
print("Running product of a list:")
for i in result:
print(i)
#Tuple
result = running_product((1,2,3,4,5,6,7))
print("Running product of a Tuple:")
for i in result:
print(i)
Sample Output:
Type of the new iterator: <class 'itertools.chain'> Running product of a list: 1 2 6 24 120 720 5040 Running product of a Tuple: 1 2 6 24 120 720 5040

Inverts a dictionary with non-unique hashable values:
Example:
def tips_collect_dictionary(obj): inv_obj = {} for key, value in obj.items(): inv_obj.setdefault(value, list()).append(key) return inv_obj ages = { "Owen": 25, "Jhon": 25, "Pepe": 15, } print(tips_collect_dictionary(ages))
Output:
{25: ['Owen', 'Jhon'], 15: ['Pepe']}
