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
