Overview of this book

This Learning Path takes you on a journey in the world of robotics and teaches you all that you can achieve with Raspberry Pi and Python. It teaches you to harness the power of Python with the Raspberry Pi 3 and the Raspberry Pi zero to build superlative automation systems that can transform your business. You will learn to create text classifiers, predict sentiment in words, and develop applications with the Tkinter library. Things will get more interesting when you build a human face detection and recognition system and a home automation system in Python, where different appliances are controlled using the Raspberry Pi. With such diverse robotics projects, you'll grasp the basics of robotics and its functions, and understand the integration of robotics with the IoT environment. By the end of this Learning Path, you will have covered everything from configuring a robotic controller, to creating a self-driven robotic vehicle using Python. • Raspberry Pi 3 Cookbook for Python Programmers - Third Edition by Tim Cox, Dr. Steven Lawrence Fernandes • Python Programming with Raspberry Pi by Sai Yamanoor, Srihari Yamanoor • Python Robotics Projects by Prof. Diwakar Vaish

Logging


Logging (https://docs.python.org/3/library/logging.html) helps with troubleshooting a problem. It helps with determining the root cause of a problem by tracing back through the sequence of events logged by the application. Let's review logging using a simple application. In order to review logging, let's review it by making a POST request:

  1. The first step in logging is setting the log file location and the log level:
       logging.basicConfig(format='%(asctime)s : %(levelname)s :
       %(message)s', filename='log_file.log', level=logging.INFO)

While initializing the logging class, we need to specify the format for logging information, errors, and so on to the file. In this case, the format is as follows:

       format='%(asctime)s : %(levelname)s : %(message)s'

The log messages are in the following format:

       2016-10-25 20:28:07,940 : INFO : Starting new HTTPS
       connection (1):
       maker.ifttt.com

The log messages are saved to a file named log_file.log.

The logging level determines...
