Python: Calculate the maximum and minimum sum of a sublist in a given list of lists
Python List: Exercise - 182 with Solution
Write a Python program to calculate the maximum and minimum sum of a sublist in a given list of lists.
Sample Solution:
Python Code:
def max_min_sublist(lst):
max_result = (max(lst, key=sum))
min_result = (min(lst, key=sum))
return max_result,min_result
nums = [[1,2,3,5], [2,3,5,4], [0,5,4,1], [3,7,2,1], [1,2,1,2]]
print("Original list:")
print(nums)
result = max_min_sublist(nums)
print("\nMaximum sum of sub list of the said list of lists:")
print(result[0])
print("\nMinimum sum of sub list of the said list of lists:")
print(result[1])
Sample Output:
Original list: [[1, 2, 3, 5], [2, 3, 5, 4], [0, 5, 4, 1], [3, 7, 2, 1], [1, 2, 1, 2]] Maximum sum of sub list of the said list of lists: [2, 3, 5, 4] Minimum sum of sub list of the said list of lists: [1, 2, 1, 2]

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")
