since stats is itself a module you first need to import it, then you can use functions from scipy.stats. import scipy import scipy.stats #now you can use scipy.stats.poisson #if you want it more accessible you could do what you did above from scipy.stats import poisson #then call poisson directly poisson Documentation¶.

1 Introduction. SciPy is a collection of mathematical algorithms and convenience functions built on the Numeric extension for Python.

0.0 To generate a sequence of random variates, we should use the size keyword argument, which is shown in the following example.

Each univariate distribution is an instance of a subclass of rv_continuous (rv_discrete for discrete distributions): The basic stats such as Min, Max, Mean and Variance takes the NumPy array as input and returns the respective results.
