python random in list code example

Example 1: python list of random values

# To create a list of random integer values:
import random
randomlist = random.sample(range(10, 30), 5)
# Output:
# [16, 19, 13, 18, 15]

# To create a list of random float numbers:
import numpy
random_float_array = numpy.random.uniform(75.5, 125.5, 2)
# Output:
# [107.50697835, 123.84889979]

Example 2: how to print a random part of a list in python

foo = ['a', 'b', 'c', 'd', 'e']

Example 3: how to randomly choose from a list python

random.choice(name of list)

Example 4: 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 5: which function to use in random module for a list in python

random.choice

Example 6: python random generator from list

n = random.random()
print(n)
