sample() is an inbuilt function of random module in Python that returns a particular length list of items chosen from the sequence i.e. list, tuple, string or set. Used for random sampling without replacement.

Syntax : random.sample(sequence, k)

Parameters:
sequence: Can be a list, tuple, string, or set.
k: An Integer value, it specify the length of a sample.

Returns: k length new list of elements chosen from the sequence.

For example,

>>> import random
>>> c = list(range(0, 10))
>>> c
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> random.sample(c, 3)
[3, 1, 0]

The use of random.sample()

  • Randomly select multiple items from any sequence such as a list.
  • Generate the sample of random integers in Python

Most commonly we use random.sample() to randomly pick more than one element from the list without repeating elements

For example, you want to pick 3 random employees from the employee list

Example:

import random

employees = ["Ault", "Jhon", "Scoot", "Eric", "Thomas", "Ela"]
sampleList = random.sample(employees, 3)
print(sampleList)

Output:

['Scoot', 'Thomas', 'Eric']

Reference: random.sample()
