Raspberry Pi for Python Programmers Cookbook - Second Edition

Overview of this book

Raspberry Pi cookbook for Python Programmers is a practical guide for getting the most out of this little computer. This book begins by guiding you through setting up the Raspberry Pi, performing tasks using Python 3 and introduces the first steps to interface with electronics. As you work through each chapter you will build up your skills and knowledge and apply them as you progress throughout the book, delving further and further into the unique abilities and features of the Raspberry Pi. Later, you will learn how to automate tasks by accessing files, build applications using the popular Tkinter library and create games by controlling graphics on screen. You will harness the power of the built-in graphics processor by using Pi3D to generate your own high quality 3D graphics and environments. Connect directly to the Raspberry Pi’s hardware pins to control electronics from switching on LEDs and responding to push buttons right through to driving motors and servos. Learn how to monitor sensors to gather real life data and to use it to control other devices, and view the results over the Internet. Apply what you have learnt by creating your own Pi-Rover or Pi-Hexipod robots. Finally, we will explore using many of the purpose built add-ons available for the Raspberry Pi, as well as interfacing with common household devices in new ways.

Organizing your photos automatically


Now that we have a class that allows us to gather information about photos, we can apply this information to perform useful tasks. In this case, we will use the file information to automatically organize a folder full of photos into a subset of folders based on the dates the photos were taken on. The following screenshot shows the output of the script:

The application will use the photo's information to sort pictures into folders by the date on which they were taken

Getting ready

You will need a selection of photos placed in a folder on the Raspberry Pi. Alternatively, you can insert a USB memory stick or a card reader with photos on it—they will be located in /mnt/. However, please make sure you test the scripts with a copy of your photos first, just in case there are any problems.

How to do it…

Create the following script in filehandler.py to automatically organize your photos:

#!/usr/bin/python3
#filehandler.py
import os
import shutil
import photohandler...
