With the help of numpy.random.exponential() method, we can get the random samples from exponential distribution and returns the numpy array of random samples by using this method.

exponential distribution

Syntax : numpy.random.exponential(scale=1.0, size=None)

Return : Return the random samples of numpy array.

Example #1 :

In this example we can see that by using numpy.random.exponential() method, we are able to get the random samples of exponential distribution and return the samples of numpy array.



Python3




# import exponential
import numpy as np
import matplotlib.pyplot as plt
  
# Using exponential() method
gfg = np.random.exponential(3.45, 10000)
  
count, bins, ignored = plt.hist(gfg, 14, density = True)
plt.show()

Output :

Example #2 :

Python3




# import exponential
import numpy as np
import matplotlib.pyplot as plt
  
# Using exponential() method
gfg = np.random.exponential(101.123, 10000)
gfg1 = np.random.exponential(gfg, 10000)
  
count, bins, ignored = plt.hist(gfg1, 14, density = True)
plt.show()

Output :
