python random sample from list code example

Example 1: sample 1 item from array python

import random
cakes = ['lemon', 'strawberry', 'chocolate']
random.choice(cakes)
# prints 1 randomly selected item from the collection of n items with 
# the probability of selection as 1/n

Example 2: python choose random sample from list

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

Example 3: python choose sample from list with replacement

import random

random.choices(list, k = 4)

Example 4: python random generator from list

import random
n = random.random()
print(n)

Example 5: random.sample python

# imports random
import random
# randint generates a random integar between the first parameter and the second
print(random.randint(1, 100))

Example 6: 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)
