1.14. Summary¶

• Computer science is the study of problem solving.

• Computer science uses abstraction as a tool for representing both processes and data.

• Abstract data types allow programmers to manage the complexity of a problem domain by hiding the details of the data.

• Python is a powerful, yet easy-to-use, object-oriented language.

• Lists, tuples, and strings are built in Python sequential collections.

• Dictionaries and sets are nonsequential collections of data.

• Classes allow programmers to implement abstract data types.

• Programmers can override standard methods as well as create new methods.

• Classes can be organized into hierarchies.

• A class constructor should always invoke the constructor of its parent before continuing on with its own data and behavior.
