Maximum element in tuple list in Python

When it is required to find the maximum element in a tuple list (i.e list of tuples), the 'max' method and the 'operator.itemgetter' method can be used.

The itemgetter fetches a specific item from its operand.

The 'max' method gives the maximum value present in an iterable that is passed as argument to it.

Below is a demonstration of the same −

Example

Live Demo

from operator import itemgetter
my_list = [('Will', 23), ('Jane', 21), ('El', 24), ('Min', 101)]

print ("The list is : ")
print(my_list)

my_result = max(my_list, key = itemgetter(1))[0]

print ("The name that has the maximum value is : ")
print(my_result)

Output

The list is :
[('Will', 23), ('Jane', 21), ('El', 24), ('Min', 101)]
The name that has the maximum value is :
Min

Explanation

• The required libraries are imported.
• The list of tuples is defined, and is displayed on the console.
• The 'max' method is used to go through the list, and specify the key as the first element of every tuple inside the list.
• This result is assigned to a value.
• It is displayed as output on the console.
