Find Maximum of K Elements in Another List Using Python

When it is required to get the maximum of K elements based on another list, a simple iteration, the ‘append’ method and the ‘max’ methods are used.

Example

Below is a demonstration of the same −

my_list_1 = [62, 25, 32, 98, 75, 12, 46, 53]
my_list_2 = [91, 42, 48, 76, 23, 17, 42, 83]

print("The first list is : " )
print(my_list_1)

print("The first list after sorting is : " )
my_list_1.sort()
print(my_list_1)

print("The second list is : " )
print(my_list_2)

print("The first list after sorting is : " )
my_list_2.sort()
print(my_list_2)

K = 42
print("The value of K is ")
print(K)

my_result = []
for index in range(len(my_list_1)):

   if my_list_2[index] == K :
      my_result.append(my_list_1[index])

my_result = max(my_result)

print("The result is : ")
print(my_result)

Output

The first list is :
[62, 25, 32, 98, 75, 12, 46, 53]
The first list after sorting is :
[12, 25, 32, 46, 53, 62, 75, 98]
The second list is :
[91, 42, 48, 76, 23, 17, 42, 83]
The first list after sorting is :
[17, 23, 42, 42, 48, 76, 83, 91]
The value of K is
42
The result is :
46

Explanation

• Two lists are defined and are displayed on the console.

• They are sorted using the ‘sort’ method and displayed on the console.

• The value of K is defined and is displayed on the console.

• An empty list is defined.

• The first list is iterated over.

• The element of a specific index in the second list is assigned to the value K.

• This element in the index of first list is appended to the empty list.

• The maximum of elements in this list is considered.

• This element is assigned to a variable.

• It is displayed as output on the console.
