Python for Finance: Analyze Big Financial Data

Conclusions

Object-oriented paradigms are an indispensible tool for modern application development.

Python provides a rather flexible framework for the definition of customer-defined classes

and for working with instances of these classes. This chapter provides only the

fundamentals of Python class definitions — Part III of the book illustrates the use of

(financial) Python classes in a more complex and realistic application scenario.

Modern application design generally builds on graphical user interfaces. The efficient

building of GUIs therefore is generally quite important, even in a rapid application

development scenario. This chapter uses the traits library, which allows simple and

efficient building of GUIs based on a Pythonic, object-oriented approach. The subsequent

chapter shows how to build GUIs based on web technologies, a technical alternative

nowadays even used for in-house applications in financial institutions.
