Python: Create the running product of an iterable
2. Running Product Iterator
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
