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

Tuples


A tuple (pronounced either like two-ple or tuh-ple) is an immutable data type that are ordered and separated by a comma. A tuple can be created as follows:

>>> my_tuple = 1, 2, 3, 4, 5

      >>> my_tuple

      (1, 2, 3, 4, 5)

Since tuples are immutable, the value at a given index cannot be modified:

>>> my_tuple[1] = 3
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: 'tuple' object does not support item assignment

A tuple can consist of a number, string, or a list. Since lists are mutable, if a list is a member of a tuple, it can be modified. For example:

>>> my_tuple = 1, 2, 3, 4, [1, 2, 4, 5]
    >>> my_tuple[4][2] = 3
    >>> my_tuple
    (1, 2, 3, 4, [1, 2, 3, 5])

Tuples are especially useful in scenarios where the value cannot be modified. Tuples are also used to return values from a function. Let's consider the following example:

>>> for value in my_dict.items...
