python choose a random element from a 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: how to print a random part of a list in python
import random
foo = ['a', 'b', 'c', 'd', 'e']
print(random.choice(foo))
Example 3: how to randomly choose from a list python
random.choice(name of list)
Example 4: 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 5: 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)
Example 6: Select an element of a list by random
import random
rand_index = random.randrange(len(list))
random_num = list[rand_index]
random_num = random.choice(list)
