Python: Find the maximum and minimum values in a given list of tuples
Python List: Exercise - 158 with Solution
Write a Python program to find the maximum and minimum values in a given list of tuples.
Sample Solution:
Python Code:
from operator import itemgetter
def max_min_list_tuples(class_students):
return_max = max(class_students,key=itemgetter(1))[1]
return_min = min(class_students,key=itemgetter(1))[1]
return return_max, return_min
class_students = [('V', 60), ('VI', 70), ('VII', 75), ('VIII', 72), ('IX', 78), ('X', 70)]
print("Original list with tuples:")
print(class_students)
print("\nMaximum and minimum values of the said list of tuples:")
print(max_min_list_tuples(class_students))
Sample Output:
Original list with tuples: [('V', 60), ('VI', 70), ('VII', 75), ('VIII', 72), ('IX', 78), ('X', 70)] Maximum and minimum values of the said list of tuples: (78, 60)

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")
