Your guide to better coding
Everything we interact with in our modern digital world has been programmed
by someone. Whether you’re sat in front of your computer, changing channels
on your TV, sending someone a text or even putting the washing machine on,
there’s some form of programming interacting with you.
Programming is everywhere. From clicking an icon on your desktop to open
a web browser to calculating the vast distances between the stars. It’s one of
the most important skills you can have in the modern world and it’s only going
to get bigger as we move into a new generation of interconnected devices
and mediums.
Starting to learn to code isn’t easy but we’re here to help you get going. In the
pages of this book you can learn how to start coding using Python, C++, Linux
scripting and FUZE BASIC with the Raspberry Pi. We cover the common pitfalls
and mistakes every coder falls into and how to avoid them in the future.
There’s a section filled with some great Python coding examples, to showing you
tips and tricks to help make the system do what you want it to; and we look at how
to get help with your code and how to test it in a safe and secure environment.
With programming you never stop learning, so Coding – Tips, Tricks & Fixes is
here to teach you what you need to continue your journey into the wonderful
world of coding.
