THE ROADSO FAR...

In the previous units, you...

In the previous projects, you used a block-based programming language to create games that involved:

• Variables
• Loops
• Conditionals

WHAT NOW?

Starting from today, you will use a text-based programming language (Python) to build on these concepts and extend them.

In the previous units, you...

Python games

Using python to make a videogame

To execute a Python game, you need a Python interpreter. This is a program that translates and executes your Python program.

SYNTAX

Programs written in a programming language must follow its syntax.

RULES THAT PRESIDE THEARRANGEMET OF WORDS IN A SENTENCE

Programs with syntax errors cannot be translated and executed.

Speech or text in a language must follow its syntax.

All programming languages have rules for syntax, i.e. how statements can be assembled.

+INFO

SYNTAX

Text vs blocks

• In Python, you can (and you will) make syntax errors. You will need to follow the syntax rules.

• Syntax errors can be frustrating when you start learning a text-based programming language.

• In block-based coding , syntax errors are not possible: rules are enforced by the blocks and the way they fit together.

• You can still make logical errors ! That’s when your program doesn’t work the way it should.

+INFO

You may be asking...

Then why do we usetext-based programming?

Because the things that you can express are infinite, and there are only so many blocks.

FIRST STEPS IN PYTHON

tASK 1: "HELLO WORLD"

Create a new project in Makecode Arcade

Type your first line of code

Reflect on this

Every time you learn a new programming language, it’s a tradition to get your first program to say “hello world”.

FIRST STEPS IN PYTHON

TASK 2: greet the user by name

Declare the variable "user"

Modify your program to show the variable

Reflect on this

Declare a variable that stores the user's name and display it on the screen.

FIRST STEPS IN PYTHON

TASK 3: greet the user by name and show their lucky number

Declare a variable named "number"

Extend the existing program from the previous task by typing in two similar additional statements.

Show the lucky number in a new splash!

FIRST STEPS IN PYTHON

GET TO KNOW THE DATA TYPES

user is a variable. It is assigned a string value.

A string is a data type used to represent text and is composed of a sequence of characters enclosed within single quotes (' ') or double quotes (" ").

a,b,c

An integer, refers to a data type used to represent whole numbers (positive, negative, or zero) without any decimal or fractional parts.

1,2,3

number is another variable. It is assigned an integer value.

It's quizz time!

Name it "Hello world!" and choose "Python only" as Code options.

Is there a Python interpreter in Makecode Arcade?

Yes, you can access to it by pressing the "Python" tab.

ORDER MATTERS

Humans can infer meaning even in cases when syntax rules are violated.For example, if you say: instead of: another human will understand. But a computer WON'T.

“tonight see you”

“see you tonight”

Make sure you:

Type this line in your program:

• Spell "game.spalsh" correctly Python is case-sensitive: using capitals makes a difference.

• Used (opening and closing) round brackets around the message to be displayed.

• Used (single or double) quotation marks around the message to be displayed.

• Type it in a new line.

• Use (single or double) quotation marks around the value of the variable.
