Summary
The variety of topics related in this chapter is quite staggering. We started with databases, graduated to Graphical User Interfaces, diverged into a discussion of XML, and ultimately built a small web application. The goal was to introduce popular, available libraries for major real-world tasks. The number of libraries available for Python 3 is steadily growing as more and more developers choose to support the cleaner syntax used in this version of the Python language. We have seen an overview of:
- SQLAlchemy for databases 
- TkInter for graphical interfaces 
- PyQt for different graphical interfaces 
- ElementTree for XML parsing 
- lxml for better XML parsing 
- CherryPy for web applications 
- Jinja for string templating in web applications 
Thus ends our tour through the world of Object-oriented Programming in Python. I sincerely hope you enjoyed the ride, and are excited to test your new skills on innovative new programming problems. Thanks for your attention, and please watch your step as you leave the...
