Python: Find maximum difference pair in a given list
Python Itertools: Exercise-43 with Solution
Write a Python program to find the maximum difference between pairs in a given list.
Sample Solution:
Python Code:
from itertools import combinations
from heapq import nlargest
def test(lst):
result = nlargest(1, combinations(lst, 2),
key=lambda sub: abs(sub[0] - sub[1]))
return result
marks = [32,14,90,10,22,42,31]
print("\nOriginal list:")
print(marks)
print("\nFind maximum difference pair of the said list:")
print(test(marks))
Sample Output:
Original list: [32, 14, 90, 10, 22, 42, 31] Find maximum difference pair of the said list: [(90, 10)]

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']}
