# Python program to randomly create N Lists of K size

When it is required to create N lists randomly that are K in size, a method is defined that shuffles the values and yields the output.

## Example

Below is a demonstration of the same

from random import shuffle def gen_random_list(my_val, K): while True: shuffle(my_val) yield my_val[:K] my_list = [12, 45, 76, 32, 45, 88, 99, 0, 1] print("The list is ") print(my_list) K, N = 4, 5 print("The value of K is ") print(K) print("The value of N is ") print(N) my_result = [] for elem in range(0, N): my_result.append(next(gen_random_list(my_list, K))) print("The result is " ) print(my_result)

## Output

The list is [12, 45, 76, 32, 45, 88, 99, 0, 1] The value of K is 4 The value of N is 5 The result is [[88, 76, 99, 12], [12, 99, 32, 76], [32, 76, 12, 99], [32, 45, 0, 12], [76, 0, 1, 45]]

## Explanation

The required packages are imported into the environment.

A method named ‘gen_random_list’ is defined that takes a value and ‘K’ as parameter.

It uses the ‘shuffle’ method and ‘yield’ operator along with slicing to give the result.

Outside the method, a list is defined and displayed on the console.

Values for K and N are defined and displayed on the console.

An empty list is defined.

The range between 0 and N is iterated over, and the method is called and the result is appended to the empty list.

This is displayed as output on the console.
