Getting Started with Python for the Internet of Things

By: Tim Cox, Steven Lawrence Fernandes, Sai Yamanoor, Srihari Yamanoor, Prof. Diwakar Vaish

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

PEP8 style guide for Python


PEP8 is a style guide for Python that helps programmers write readable code. It is important to follow certain conventions to make our code readable. Some examples of coding conventions include the following:

  • Inline comments should start with a and be followed by a single space.
  • Variables should have the following convention: first_var.
  • Avoiding trailing whitespaces on each line. For example, if name == "test": should not be followed by whitespaces.

Note

You can read the entire PEP8 standards at https://www.python.org/dev/peps/pep-0008/#block-comments.

Verifying PEP8 guidelines

There are tools to verify PEP8 standards of your code. After writing a code sample, ensure that your code adheres to PEP8 standards. This can be done using the pep8 package. It can be installed as follows:

pip3 install pep8

Let's check whether one of our code samples has been written according to the PEP8 convention. This can be done as follows:

pep8 opencv_test.py

The check indicated the following...
