Introduction to Python packages – scipy

The submodule from the scipy package is called scipy.cluster. With the following code, we can find all embedded functions. The document for this submodule is available here at https://docs.scipy.org/doc/scipy/reference/cluster.hierarchy.html:

import scipy.cluster as cluster 
x=dir(cluster) 
print(x) 

The next screenshot shows the related output:

First, we use the scipy.cluster._hierarchy function. This example is borrowed as well (https://stackoverflow.com/questions/21638130/tutorial-for-scipy-cluster-hierarchy). The code is shown here:

import numpy as np 
import matplotlib.pyplot as plt 
import scipy.cluster.hierarchy as hac 
a = np.array([[0.11, 2.5],[1.45, 0.40], 
              [0.3,  1.1],[0.9 , 0.8], 
              [0.5,  0.01],[0.1 , 0.5], 
              [0.6,  0.5],[2.6,  2.1], 
              [2.3,  3.2],[3.1,  2.2], 
   ...
