Python random betavariate()


This article demonstrates how to use random.betavariate function. betavariate() is an inbuilt method of the random module. It is used to return a random floating point number with beta distribution. The returned value is between 0 and 1.


Syntax :

random.betavariate(alpha,beta)


Parameter Values :

ParameterDescription
alphaRequired. Greater than 0.
betaRequired. Greater than 0.


Return Value :

a random beta distribution floating number between 0 and 1

Example :

1.

# import the random module 
import random 

# determining the values of the parameters 
alpha = 5
beta = 10

# using the betavariate() method 
print(random.betavariate(alpha, beta)) 

Output :

0.3249647433432424


2.
We can generate the number multiple times and plot a graph to observe the beta     distribution.
# import the required libraries 
import random 
import matplotlib.pyplot as plt 


# store the random numbers in a 
# list 
nums = [] 
alpha = 5
beta = 10

for i in range(100): 
    temp = random.betavariate(alpha, beta) 
    nums.append(temp) 
    
# plotting a graph 
plt.plot(nums) 
plt.show()

Output :
