Figure 16
In the preceding screenshot, we have created two Python modules, State.py and StateTest.py. The State.py module will contain the code for the three search ingredients mentioned in the previous section. The StateTest module is a file where we can test these ingredients.
Let's go ahead and create a constructor and a function that returns an initial state, as shown in the following code:
....import os
