The configuration for the previous code is shown here:

I’ll now discuss the previous code in brief. It has a root class that is an
abstract class. It contains essential attributes such as a base URL and a
page limit; these are essential for all child classes. It also contains common
logic in class method functions such as the download URL, print output,
and read configuration. It also has an abstract method collectThoughts,
which must be implemented in child classes. This abstract method is
passing on a common behavior to every child class that all of them must
collect thoughts from the Web. Implementations of this thought collection
are child specific.
Calling Other Languages in Python
Now I will describe how to use other languages’ code in Python. There are
two examples here; one is calling R code from Python. R code is required
for some use cases. For example, if you want a ready-made function for the
Holt-Winter method in a time series, it is difficult to do in Python. But it is
