# 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
```

## Python: Tips of the Day

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']}
```
