random.gauss() function in Python

random module is used to generate random numbers in Python. Not actually random, rather this is used to generate pseudo-random numbers. That implies that these randomly generated numbers can be determined.

random.gauss()

gauss() is an inbuilt method of the random module. It is used to return a random floating point number with gaussian distribution.

Syntax : random.gauss(mu, sigma)

Parameters :
mu : mean
sigma : standard deviation

Returns : a random gaussian distribution floating number

Example 1:




# import the random module
import random
  
# determining the values of the parameters
mu = 100
sigma = 50
  
# using the gauss() method
print(random.gauss(mu, sigma))


Output :

127.80261974806497

Example 2: We can generate the number multiple times and plot a graph to observe the gaussian distribution.




# import the required libraries 
import random 
import matplotlib.pyplot as plt 
    
# store the random numbers in a  
# list 
nums = [] 
mu = 100
sigma = 50
    
for i in range(100): 
    temp = random.gauss(mu, sigma)
    nums.append(temp) 
        
# plotting a graph 
plt.plot(nums) 
plt.show()


Output :

Example 3: We can create a histogram to observe the density of the gaussian distribution.




# import the required libraries 
import random 
import matplotlib.pyplot as plt 
    
# store the random numbers in a list 
nums = [] 
mu = 100
sigma = 50
    
for i in range(10000): 
    temp = random.gauss(mu, sigma) 
    nums.append(temp) 
        
# plotting a graph 
plt.hist(nums, bins = 200) 
plt.show()


Output :
