how to choose a random number in a list python 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: 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 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)
