python random choice in list code example

Example 1: python choose random element from list

import random

#1.A single element
random.choice(list)

#2.Multiple elements with replacement
random.choices(list, k = 4)

#3.Multiple elements without replacement
random.sample(list, 4)

Example 2: python random choice from list

import random
list = [20, 30, 40, 50 ,60, 70, 80]
sampling = random.choices(list, k=4)      # Choices with repetition
sampling = random.sample(list, k=4)       # Choices without repetition

Example 3: 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)
