Shuffle a Python list

This post will discuss how to shuffle a list in Python. The solution should in-place shuffle the contents of a list.

1. Using `random.shuffle`

The standard solution to shuffle a list in Python is to use the shuffle() function from the random module. This is demonstrated below:

from random import shuffle

if __name__ == '__main__':

nums = list(range(10))

shuffle(nums)

print(nums)

2. Using `random.sample`

The shuffle() function shuffles the list in-place, i.e., the elements are rearranged within the list. To shuffle an immutable list, use sample() instead, which would return a new randomized list. This is demonstrated below:

from random import sample

if __name__ == '__main__':

nums = range(10)

l = sample(nums, len(nums))

print(l)

3. Using `numpy.random.shuffle`

If you’re using the NumPy library, consider using numpy.random.shuffle. It modifies the list in-place by shuffling its contents.

import numpy as np

if __name__ == '__main__':

nums = list(range(10))

np.random.shuffle(nums)

print(nums)
