Python: Find the maximum, minimum aggregation pair in given list of integers
Python Itertools: Exercise-28 with Solution
Write a Python program to find the maximum, minimum aggregation pair in given list of integers.
Sample Solution:
Python Code:
from itertools import combinations
def max_aggregate(l_data):
max_pair = max(combinations(l_data, 2), key = lambda pair: pair[0] + pair[1])
min_pair = min(combinations(l_data, 2), key = lambda pair: pair[0] + pair[1])
return max_pair,min_pair
nums = [1,3,4,5,4,7,9,11,10,9]
print("Original list:")
print(nums)
result = max_aggregate(nums)
print("\nMaximum aggregation pair of the said list of tuple pair:")
print(result[0])
print("\nMinimum aggregation pair of the said list of tuple pair:")
print(result[1])
Sample Output:
Original list: [1, 3, 4, 5, 4, 7, 9, 11, 10, 9] Maximum aggregation pair of the said list of tuple pair: (11, 10) Minimum aggregation pair of the said list of tuple pair: (1, 3)

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
