PY-L1-01 · Welcome to Python — Advaslearning Hub

⚙ Setup

Before We Begin · Get Python Running

One-time

Pick one of the two paths below. Path A is best for home laptops. Path B works on any computer with a browser — even a school Chromebook.

Path A · Install on your laptop

Python + VS Code (recommended)

A one-off install. After this you can code offline, save files locally, and run anything we cover in this course.

Install Python
- Open python.org/downloads and click the big yellow Download Python 3.x button.
- Windows users — important: on the first installer screen, tick Add python.exe to PATH, then click Install Now.
- macOS users: open the downloaded .pkg file and follow the prompts.
- To check it worked, open a terminal (Windows: Command Prompt; macOS: Terminal) and type python --version. You should see a line like Python 3.12.4.
Install Visual Studio Code (VS Code)
- Open code.visualstudio.com.
- Click the big blue download button — it picks the right version for your computer.
- Run the installer, then open VS Code from your Start Menu (Windows) or Applications (macOS).
Add the Python extension to VS Code
- In VS Code, click the Extensions icon on the left sidebar (four squares — or press Ctrl + Shift + X on Windows / ⌘ + Shift + X on macOS).
- Search for Python.
- Install the one published by Microsoft (it has a small blue tick and millions of downloads).
Try it
- Make a folder somewhere called python-lessons.
- In VS Code: File → Open Folder, then choose that folder.
- File → New File, save it as hello.py.
- Type print("Hello!") and click the green ▶ Run button (top-right corner).
- You should see Hello! in the terminal panel at the bottom.

Path B · No install needed

Use an online editor in your browser

Perfect for school laptops, Chromebooks, or if you just want to start coding right now.

Open the online editor
- Go to online-python.com in any browser.
- You will see a code area on the left and an output area on the right.
Run your first line
- Delete any starter code you see.
- Type print("Hello!").
- Click the green Run button at the top.
- You should see Hello! appear on the right.
Save your work
- Online editors do not save your code when you close the tab.
- For each lesson, copy your code into a Google Doc, Word file, or text file before closing the browser.

Stuck?

If something does not work — wrong version, missing button, scary error message — write down exactly what the screen says and ask in class. Setup hiccups are common; we will sort it out together.

Learning Goals

3 min

By the end of this lesson you can:

Open your editor and find the place to type Python.
Use print() to make Python show a message.
Display words and numbers from a single line of code.

Warm-Up

5 min

This is our very first lesson, so we have nothing to recap. Instead, here is a thought puzzle.

Imagine a robot that only does what you say, word for word. You want it to greet you out loud.

What is the exact sentence you would tell the robot? Write it on paper and share with the class.

Tip

Python is very much like that robot. It does exactly what we type — nothing more, nothing less.

New Concept · Saying Hello with print()

12 min

What is Python?

Python is a language we use to give computers instructions. It is friendly, neat, and easy to read.

Big teams use it every day — Netflix, Instagram, NASA, and many schools right here in the UK.

print() — Python's loudspeaker

The command print() tells Python to show something on the screen.

We put what we want to show inside the round brackets. To show words, we wrap them in quotes:

print("Hello!")

The arrow # → shows what Python prints back to us.

Lines starting with # are called comments. Python ignores them — they are notes for humans.

Numbers don't need quotes

For numbers, no quotes are needed:

print(7)

An empty print() makes a blank line

Calling print() with nothing inside prints a blank line. Useful for spacing!

print("Top line")
print()
print("Bottom line")

Worked Example · A Tiny Greeting Card

12 min

Open VS Code (or online-python.com if you chose Path B in the Setup section). Type these five lines exactly, then press Run.

Code

print("Hello, world!")
print("My name is Aisyah.")
print("I am 12 years old.")
print()
print("Today I learn Python!")

Python should print this in the bottom panel:

Output

Hello, world!
My name is Aisyah.
I am 12 years old.

Today I learn Python!

Mixing words and numbers

We can put more than one item inside print() — separate them with a comma:

print("Two plus three equals", 2 + 3)

Python adds a single space between each item.

Notice that 2 + 3 has no quotes, so Python does the maths.

Watch out

Quotes change everything. print("2 + 3") shows the words 2 + 3 — Python does no maths.

Try It Yourself

13 min

Type each task into your editor. Run it. Fix any typos before moving on.

01 Print three lines

Print three lines: your first name, your favourite hobby, and the city you live in.

Hint

Use three separate print() commands. Wrap each piece of text in quotes.

02 Show your age

Print the words I am followed by your age as a real number — not inside quotes.

Hint

Use a comma inside print(), like print("I am", 12).

03 Tiny maths poem

Write four print() lines that tell us about your week.

At least one line must include a sum, like print("Days in a fortnight:", 7 + 7).

Hint

Mix quotes and numbers. The + only adds when both sides are numbers.

Mini-Challenge · Self-Introduction Card

8 min

Build a tidy four-line introduction that mixes words and numbers in a single Python file.

Your card must include:

A friendly greeting line.
Your name.
Your age — printed as a real number, not inside quotes.
One line that does a calculation, such as 2026 - 2014.

Stretch goal. Add a blank line between the greeting and the rest, using empty print().

Show one possible solution

print("Hi! Welcome to my card.")
print()
print("My name is Aiman.")
print("I am", 12, "years old.")
print("That is roughly", 12 * 365, "days alive!")

Recap

3 min

Today we taught Python to speak. We used print() to show words and numbers, and joined them with commas.

Vocabulary Card

print(): Python's command for showing something on screen.
string: Letters or words wrapped in quotes, like "Hello".
comment: A line starting with #. Python ignores it; it is just for humans.

Homework

4 min

Write a five-line poem about your week using print(). At least one line must include a number.

Save the file as my_week.py. Bring it to the next lesson — we will share favourites!

Sample · my_week.py

# my_week.py — a tiny poem about my week

print("On Monday I learn Python at school.")
print("On Tuesday I read 2 books at the library.")
print("On Wednesday I share roti canai with friends.")
print("On Thursday I help cook nasi lemak at home.")
print("On Friday I rest — what a busy week!")

Yours doesn't need to match exactly. Five print() lines and at least one number is enough!
