Python: Find the maximum and minimum product from the pairs of tuple within a given list

Python List: Exercise - 124 with Solution

Write a Python program to find the maximum and minimum product from the pairs of tuple within a given list.

Sample Solution:

Python Code:

def tuple_max_val(nums):
    result_max = max([abs(x * y) for x, y in nums] )
    result_min = min([abs(x * y) for x, y in nums] )
    return result_max,result_min
nums = [(2, 7), (2, 6), (1, 8), (4, 9)]   
print("The original list, tuple : ") 
print(nums)
print("\nMaximum and minimum product from the pairs of the said tuple of list:")
print(tuple_max_val(nums)) 

Sample Output:

The original list, tuple : 
[(2, 7), (2, 6), (1, 8), (4, 9)]

Maximum and minimum product from the pairs of the said tuple of list:
(36, 8)

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")
