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’.
