Summary
In this chapter, we discussed a variety of topics that require the use of advanced Python modules and libraries. We started by refreshing our knowledge about data containers in Python. Next, we learned how to use and build iterators for iterable objects. We also covered generators, which are more efficient and easier to build and use than iterators. We discussed how to open and read from files and how to write to files, followed by the use of a context manager with files. In the next topic, we discussed how to handle errors and exceptions in Python, how to raise exceptions through programming, and how to define custom exceptions. Exception handling is fundamental to any decent Python application. In the last section, we covered how to configure the logging framework in Python using different options for handlers and formatters.
After going through this chapter, you now know how to build your own iterators and design generator functions to iterate on any iterable object,...
