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 deviationReturns : a random gaussian distribution floating number
Example 1:
# import the random moduleimport random  # determining the values of the parametersmu = 100sigma = 50  # using the gauss() methodprint(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 = 100sigma = 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 = 100sigma = 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 :
