python – Get a random sample with replacement

In Python 3.6, the new random.choices() function will address the problem directly:

>>> from random import choices
>>> colors = [R, G, B, Y]
>>> choices(colors, k=4)
[G, R, G, Y]

With random.choice:

print([random.choice(colors) for _ in colors])

If the number of values you need does not correspond to the number of values in the list, then use range:

print([random.choice(colors) for _ in range(7)])

From Python 3.6 onwards you can also use random.choices (plural) and specify the number of values you need as the k argument.

Try numpy.random.choice (documentation numpy-v1.13):

import numpy as np
n = 10 #size of the sample you want
print(np.random.choice(colors,n))
