how to choose a random value from a list in 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: 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 4: pick a random number from a list in python

import random

numberList = [1,2,3,4,5]
print(random.choice(numberList))    # Prints a random number from the list

Example 5: place a number randomly in a list python

offsetBiasSample = [randint(-10,10)/100 for i in range(10)]
offsetBias = choice(offsetBiasSample)
index_offsetBias = randint(0,len(oldBiases)-1)
oldBiases[index_offsetBias] = oldBiases[index_offsetBias] + offsetBias
