numpy random number between 0 and 1 code example

Example 1: python randomise between 0 or 1

import random
random.random() # Gives you a number BETWEEN 0 and 1 as a float
round(random.random()) # Gives you a number EITHER 0 and 1

Example 2: numpy random int

np.random.randint(2, size=10) # Creates binary sample of size 10
np.random.randint(5, size=10) # Creates sample with 0-4 as values of size 10

np.random.randint(5, size=(2, 4))

Example 3: numpy random float array between 0 and 1

# Returns an array of floats between 0 and 10 of size 15
np.random.uniform(low=0, high=10, size=15)

Example 4: random python between 0 and 1

import random
random.random() # Gives you a number between 0 and 1

Example 5: numpy random array between 0 and 1

>>> np.random.rand(3,2)
array([[ 0.14022471,  0.96360618],  #random
       [ 0.37601032,  0.25528411],  #random
       [ 0.49313049,  0.94909878]]) #random
