**RANDOM.SAMPLE( )**\
We used the random.sample() list previously when we created our Password Generator. To brush up on this module:\
**random.sample(\<list\_name/set>,     \<how\_many\_to\_choose\_from\_the\_list*****)***

{% hint style="info" %}
Python’s random module provides random.sample() function for random sampling and **randomly pick more than one element from the list without repeating elements**. The random.sample() returns a list of unique elements chosen randomly from the list, sequence, or set, we call it random sampling without replacement.

In simple terms, for example, you have a list of 100 names, and you want to choose ten names randomly from it without repeating names, then you must use random.sample().

**`random.sample(population, k)`**

The `random.sample()` function has two arguments, and both are required.

* The `population` can be any sequence such as list, set from which you want to select a `k` length number.
* The `k` is the number of random items you want to select from the sequence.  `k` must be less than the size of the specified list.
* A `random.sample()` function raises a type error if you miss any of the required arguments.

The `random.sample()` returns a new list containing the randomly selected item\
**Example**

**`import random`**\
**`num_list = [20, 40, 80, 100, 120]`** \
\&#xNAN;**`print ("Choosing 3 random items from a list using random.sample() function")`** \
**`new_random_list = random.sample(num_list, 3) print(sampled_list`**

**`Choosing 3 random items from a list using random.sample() function`**&#x20;

**`[40. 120, 80]`**
{% endhint %}

**RANDOM.CHOICE( ) & RANDOM.CHOICES( )**\
The main difference between 'sample' and 'choice', is that 'choice' only returns a SINGLE item from a  list UNLESS you use the random.choices( ) function.\
This can return multiple items AND CAN also return REPEATED items OR it CAN REPEAT ELEMENTS

{% hint style="info" %}
**`import random`**\
**`numbers = list(range(10))`**\
**`print(random.choices(numbers, 10))`**\
\
**`Output`**\
**`[3, 6, 8, 4, 2, 1, 0, 5, 9, 7]`**\
\
**`AN INTERESTING DIFFERENCE BETWEEN CHOICES AND SAMPLE (APART FROM THE ABOVE COMPARISON IS THAT WITH CHOICES YOU CAN GET MORE RETURNS THAN WHAT IS INITIALLY IN THE LIST>`**\
**`FOR EXAMPLE:`**
