Python – Random insertion of elements K times

When it is required to randomly insert elements K times, the ‘random’ package and methods from the random package along with a simple iteration is used.

Example

Below is a demonstration of the same −

import random

my_list = [34, 12, 21, 56, 8, 9, 0, 3, 41, 11, 90]

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

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

to_add_list = ["Python", "Object", "oriented", "language", 'cool']

K = 3
print("The value of K is ")
print(K)

for element in range(K):
   index = random.randint(0, len(my_list))
   my_list = my_list[:index] + [random.choice(to_add_list)] + my_list[index:]

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

Output

The list is :
[34, 12, 21, 56, 8, 9, 0, 3, 41, 11, 90]
The list after sorting is :
[0, 3, 8, 9, 11, 12, 21, 34, 41, 56, 90]
The value of K is
3
The resultant list is :
[0, 3, 8, 9, 11, 12, 'Python', 21, 34, 41, 56, 90, 'Object', 'oriented']

Explanation

• The required packages are imported into the environment.

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

• It is sorted using the ‘sort’ method and is displayed on the console again.

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

• The value of K is iterated over, and the ‘randint’ from the ‘random’ package is used to generate the elements of the index.

• The list indexing and the ‘choice’ method from the ‘random’ package is used to add values to the list using the concatenation operator.

• This list is displayed as the output on the console.
