Let's program
In this chapter, we will get you familiar with Python and how you can use the GPIOs on this device. To do this, go ahead and click on the Raspberry icon in the top left-hand corner. You will see the Python console 3.0. There could be an older version of Python as well. We will be using the newer version in this book.
Once the window opens, you will see the playground where you would be doing the coding. So now we are ready to write the first code for Python Robotics. Now let's see how it's done.
The first thing we will write is:
Almost all of the time when we start writing a program, we will start by writing the preceding line. Now, before we understand what it does, we need to understand libraries. Often while we are writing code, we will have to write the code again and again in multiple places. This takes a lot of time and certainly is not cool!
So, to solve this problem, we created functions. A function is a miniature program that we might think would be used over and over...
