Python: Find the minimum, maximum value for each tuple position in a given list of tuples

Python List: Exercise - 175 with Solution

Write a Python program to find the minimum, maximum value for each tuple position in a given list of tuples.

Sample Solution:

Python Code:

def max_min_list_tuples(nums):
    zip(*nums)
    result1 = map(max, zip(*nums))
    result2 = map(min, zip(*nums))
    return list(result1), list(result2)

nums = [(2,3),(2,4),(0,6),(7,1)]
print("Original list:")
print(nums)

result = max_min_list_tuples(nums)
print("\nMaximum value  for each tuple position in the said list of tuples:")
print(result[0])
print("\nMinimum value  for each tuple position in the said list of tuples:")
print(result[1])

Sample Output:

Original list:
[(2, 3), (2, 4), (0, 6), (7, 1)]

Maximum value  for each tuple position in the said list of tuples:
[7, 6]

Minimum value  for each tuple position in the said list of tuples:
[0, 1]

Flowchart:

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")
