A quick look at the iSAX Python package

In this section, we will take a first look at the iSAX Python package to get a better idea of the supported functionality. Although we will begin with the code from the sax package we developed in Chapter 2, we are going to rename that package isax and create additional source code, which is named isax.py.

The structure of the isax directory with the Python files is going to be as follows:

$ tree isax/
isax/
├── SAXalphabet
├── __init__.py
├── isax.py
├── sax.py
├── tools.py
└── variables.py
1 directory, 6 files

So, in total, we have six files. You already know five of them from the sax package. The only new one is the isax.py source code file, which is the core file for this chapter. Additionally, we are going to add more global variables to the variables.py file and some functions to tools.py.
