STARTING WITH PYTHON

Meet Python

Python is one of the most popular computer

programming languages in the world. It was

first released in the 1990s and is now used to

build millions of apps, games, and websites.

Why Python?

Python is a great language for getting started

with computer programming. Many schools

and universities use it to teach coding. Here

are some of the reasons that Python’s so useful.

It’s easy to read

and write!

△ Easy to read and write

Python is a text-based computer programming

language. You write the instructions using a

mixture of English words, punctuation characters,

symbols, and numbers. This makes Python code

simple to read, write, and understand.

▽ Batteries included

Programmers say Python has “batteries

included.” This is because it comes with

everything you need to start coding

right away.

△ Works everywhere

Python is portable. This means you can write and

run Python code on lots of different computers.

The same Python code will work on PCs, Macs,

Linux machines, and Raspberry Pi computers. The

programs behave the same way on each machine.

▷ Great support

Python has well-written

documentation. It has a

guide to getting started, a

reference section for looking

up what things mean, and

a bunch of example code.

△ Handy tools

Python is packed with lots of useful tools and

preprogrammed code that you can use in your

programs. This is called the Standard Library.

Using these tools makes it easier and quicker

for you to build your own programs.

LINGO

Python

Python isn’t named after the type of

snake. It’s actually named after a

British comedy group called “Monty

Python’s Flying Circus.” The creator of

Python, Guido van Rossum, was a big

fan of the group and their quirky

humor. Python programmers often

use the group’s jokes and famous

quotes in their code as a tribute.

STARTING WITH PYTHON

Installing Python

All the projects in this book use Python 3, so

make sure you download the correct version

from the website. Follow the instructions

that match your computer.

Open IDLE

When the installation is finished, check that it was

successful by opening the IDLE program. Go to the

“Start” menu, choose “All Apps”, then select “IDLE”.

A window like the one below should open up.

Download Python

Click on the latest version of Python for Windows,

beginning with the number 3. The installer file will

download automatically. Of the different installer

options, select “executable installer”.

Go to the Python website

Type the address below into your web

browser to go to the Python website.

Then click on “Downloads” to open the

download page.

Python on Windows

Before you install Python 3 on a Windows PC, find out

if it uses the 32-bit or 64-bit version of windows. Click

“Start”, right-click “Computer”, and left-click “Properties”.

Then choose “System” if the option appears.

If you have a 32-bit

version of Windows,

use this installer.

If you have a 64-bit

version of Windows,

use this installer.

Click the

installer.

Run the installer

Double-click the installer file to install Python.

Choose “install for all users” and click “next” at each

prompt, without changing the default settings.

LINGO

IDLE

IDLE (short for Integrated

Development Environment) is

a free app that you get when

you install Python. Designed for

beginners, IDLE includes a basic

text editor that allows you to write

and edit Python code.

Python 3.6.0a4 (v3.6.0a4:017cf260936b, Aug 15 2016, 00:45:10) [MSC v.1900 32

bit (Intel)] on win32

Type "copyright", "credits" or "license()" for more information.
