# Python: Find the pairs of maximum and minimum product from a given list, use itertools module

## Python Itertools: Exercise-33 with Solution

Write a Python program to find pairs of maximum and minimum products from a given list. Use the itertools module.

Sample Solution:

Python Code:

``````import itertools as it
def list_max_min_pair(nums):
result_max = max(it.combinations(nums, 2), key = lambda sub: sub[0] * sub[1])
result_min = min(it.combinations(nums, 2), key = lambda sub: sub[0] * sub[1])
return result_max, result_min

nums = [2,5,8,7,4,3,1,9,10,1]
print("The original list: ")
print(nums)
print("\nPairs of maximum and minimum product from the said list:")
print(list_max_min_pair(nums))
```
```

Sample Output:

```The original list:
[2, 5, 8, 7, 4, 3, 1, 9, 10, 1]

Pairs of maximum and minimum product from the said list:
((9, 10), (1, 1))
```

## 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']}
```
