Last Updated :

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)
Parameters :
alpha : greater than 0
beta : greater than 0
Returns : a random beta distribution floating number between 0 and 1
Example 1:
import random
alpha = 5
beta = 10
print (random.betavariate(alpha, beta))
|
Output :
0.5148685287422776
Example 2: We can generate the number multiple times and plot a graph to observe the beta distribution.
import random
import matplotlib.pyplot as plt
nums = []
low = 10
high = 100
mode = 20
for i in range ( 100 ):
temp = random.betavariate( 5 , 10 )
nums.append(temp)
plt.plot(nums)
plt.show()
