Python Program to replace list elements within a range with a given number

PythonServer Side ProgrammingProgramming

When it is required to replace list elements within a range with a given number, list slicing is used.

Example

Below is a demonstration of the same

my_list = [42, 42, 18, 73, 11, 28, 29, 0, 10, 16, 22, 53, 41]

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

i, j = 4, 8
my_key = 9

my_list[i:j] = [my_key] * (j - i)

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

Output

The list is :
[42, 42, 18, 73, 11, 28, 29, 0, 10, 16, 22, 53, 41]
The result is:
[42, 42, 18, 73, 9, 9, 9, 9, 10, 16, 22, 53, 41]

Explanation

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

  • Two integers are defined, and an integer is defined.

  • The key is multiplied with the difference between the two integers.

  • It is assigned to the sliced indices.

  • This is the output that is displayed on the console.
