Let us now take a look at all the methods to solve the given problem. In the previous article, you might have seen that we solved this problem using a recursive approach.

## Method 1: Using a random() library

import random lst = [] n = int(input("Enter number of elements : ")) for i in range(0, n): ele = int(input()) lst.append(ele) print("List entered by the user (without shuffling): ", lst) for i in range(len(lst)-1, 0, -1): j = random.randint(0, i + 1) lst[i], lst[j] = lst[j], lst[i] print("Here is the shuffled list: ", lst)

**Output:**

```
Enter number of elements : 8
11
6
35
26
95
63
45
2
List entered by the user (without shuffling): [11, 6, 35, 26, 95, 63, 45, 2]
Here is the shuffled list: [35, 95, 6, 2, 26, 63, 45, 11]
```

**Explanation:**

Here we initialized a for loop to perform the swapping among the elements of the list.

## Method 2: Using random. shuffle()

import random lst = [] n = int(input("Enter number of elements : ")) for i in range(0, n): ele = int(input()) lst.append(ele) print("List entered by the user (without shuffling): ", lst) random.shuffle(lst) print ("The shuffled list is : " + str(lst))

**Explanation:**

Here in this method we simply used the shuffle function of the random library. This is one of the simplest methods to solve this problem.

## Method 3: Using random. sample()

import random lst = [] n = int(input("Enter number of elements : ")) for i in range(0, n): ele = int(input()) lst.append(ele) print("List entered by the user (without shuffling): ", lst) result = random.sample(lst, len(lst)) print ("The shuffled list is : ", result)

**Explanation:**

Here in this method, we used the sample function of the random library. The built-in function sample() of the random module in Python returns a certain length list of objects selected from the sequence, such as a list, tuple, string, or set. used for replacement-free random sampling.

## Method 3: Using the randint() function

import random lst = [] n = int(input("Enter number of elements : ")) for i in range(0, n): ele = int(input()) lst.append(ele) print("List entered by the user (without shuffling): ", lst) n = len(lst) for i in range(n): j = random.randint(0, n-1) element=lst.pop(j) lst.append(element) print ("The shuffled list is : ", lst)

**Output:**

```
Enter number of elements : 6
1
2
3
4
5
6
List entered by the user (without shuffling): [1, 2, 3, 4, 5, 6]
The shuffled list is : [2, 3, 5, 4, 1, 6]
```

**Explanation:**

Here we used the randint() function to generate a random set of integers in between the range of 0 to the length of the list. This function will generate the random integer and that integer will be taken as an index to pop out the elements in the list.
