Python program to replace first ‘K’ elements by ‘N’

When it is required to replace first ‘K’ elements by ‘N’, a simple iteration is used.

Example

Below is a demonstration of the same −

my_list = [13, 34, 26, 58, 14, 32, 16, 89] print("The list is :") print(my_list) K = 2 print("The value of K is :") print(K) N = 99 print("The value of N is :") print(N) for index in range(K): my_list[index] = N print("The result is :") print(my_list)

Output

The list is : [13, 34, 26, 58, 14, 32, 16, 89] The value of K is : 2 The value of N is : 99 The result is : [99, 99, 26, 58, 14, 32, 16, 89]

Explanation

• A list of integers is defined and is displayed on the console.

• The value for ‘K’ and ‘N’ are defined and displayed on the console.

• The range within ‘K’ is iterated over, and every element in the index is assigned the value of N.

• This is done up to the values within index ‘K’.
