Python | Numpy np.lognormal() method Last Updated : 13 Oct, 2019 Comments Improve Suggest changes Like Article Like Report With the help of np.lognormal() method, we can get the log normal distribution values using np.lognormal() method. Syntax : np.lognormal(mean, sigma, size) Return : Return the array of log normal distribution. Example #1 : In this example we can see that by using np.lognormal() method, we are able to get the log normal distribution using this method.
