random value array python code example

Example 1: how to get a random element from an array in python

import random
names=['Mark', 'Sam', 'Henry']

#Set any array
random_array_item=random.choice(names)

#Declare a variable as a random choice
print(random_array_item)

#Print the random choice
#Or, if you want to arrange them in any order:
for j in range(names):
  print(random.choice(names))

Example 2: select random value from list python

import random

# with replacement = same item CAN be chosen more than once.
# without replacement = same item CANNOT be chosen more then once.

# Randomly select 2 elements from list without replacement and return a list
random.sample(list_name, 2)

# Randomly select 3 elements from list with replacement and return a list
random.choices(set_name, k=3)

# Returns 1 random element from list
random.choice(list_name)
