Mobile Python: Rapid Prototyping of Applications on the Mobile Platform

6.6. Summary

In this chapter, we have gone through many new concepts, including:

• the directory hierarchy on the S60 platform

• making directories

• handling error conditions

• reading and writing files

• reading sounds, photos and videos

• the dictionary object

• handling Unicode conversions

• using a local database

• positioning techniques

• using a timer object.

By no means do you have to learn all these techniques at once. Feel free to use this chapter as a reference and come back to it whenever you need to apply these concepts in practice. Many of these ideas, such as reading and writing files and handling error conditions, are not specific to PyS60 but they apply to the Python language in general. Thus, you will find plenty of help on the web regarding these subjects.

Even though these techniques might not feel as intriguing at first sight as graphics and sounds, they form the basic scaffolding for any non-trivial application. Luckily, as you might have noticed, PyS60 makes this scaffolding extremely lightweight and transparent, so you can really focus on the things that are important to you.
