mean and variance computation for Gaussian, exponential and uniform distributions code example

Example: Generate random numbers following Poisson distribution, Geometric Distribution, Uniform Distribution, and Normal Distribution, and plot them

from scipy.stats import poisson
data_poisson = poisson.rvs(mu=3, size=10000)
ax = sns.distplot(data_poisson,
                  bins=30,
                  kde=False,
                  color='skyblue',
                  hist_kws={"linewidth": 15,'alpha':1})
ax.set(xlabel='Poisson Distribution', ylabel='Frequency')
