python sampling elements from a vector code example

Example 1: python choose sample from list with replacement

import random

random.choices(list, k = 4)

Example 2: python choose random sample from list

import random
sequence = [i for i in range(20)]
subset = sample(sequence, 5) #5 is the lenth of the sample
print(subset) # prints 5 random numbers from sequence (without replacement)
