### 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 = 5beta = 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 = 5beta = 10for i in range(100):     temp = random.betavariate(alpha, beta)     nums.append(temp)     # plotting a graph plt.plot(nums) plt.show()`
