# Select Random Element from Set in Python

In this article, we will see **how to select a random element from a set in Python**.

We have the **random module **in Python which implements pseudo-random number generators for various distributions including integer, float.

Also, we will see to randomly select multiple choices from a set.

## Random number operations in set in Python

### random.choice()

This function retrieves a single element from the set.

# program using choice() function import random set = (11, 22, 33, 44, 55, 66, 77, 88) print("A random number from the set is: " , random.choice(set))

**Output: **

A random number from the set is: 77

### random.choices()

As we know random.choice() is used for selecting single element whereas random.choices() is used to select multiple elements specified in its argument. This function takes 2 arguments, set_name and k(number of random items)

import random movie_list = ('Godfather', 'Modern Times', 'Casablanca', 'Metropolis', 'Mary Poppins', 'Spartacus') item = random.choices(movie_list, k=2) print("Randomly selected items from movie_list are: ", item)

**Output:**

Randomly selected items from movie_list are: ['Spartacus', 'Godfather']

### random.sample()

Likewise, **random.sample() **can be used instead **random.choices()**. Both arguments and output for random.sample() are similar to random.chocies().

import random movie_list = ('Godfather', 'Modern Times', 'Casablanca', 'Metropolis', 'Mary Poppins', 'Spartacus') item = random.sample(movie_list, k=2) print("Randomly selected items from movie_list are: ", item)

**Output:**

Randomly selected items from movie_list are: ['Metropolis', 'Casablanca']

## randrange()

Furthermore, many times we need an item from a set along with its index position. We can accomplish it by making use of **randrange()** function. So let us now see how randomly chose an item along with its index number.

from random import randrange movie_list = ('Godfather', 'Modern Times', 'Casablanca', 'Metropolis', 'Mary Poppins', 'Spartacus') random_index = randrange(len(movie_list)) movie_item = movie_list[random_index] print ("Randomly selected item and its index is - ", movie_item, "\nIndex - ", random_index)

**Output:**

Randomly selected item and its index is - Casablanca Index - 2
