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")
