Unlocking Variables: The Containers That Power Your Code — ICT

Unlocking Variables: The Containers That Power Your Code

Companion summary

Have you ever wondered how a game remembers your score, even as it changes every second? Every app you use — from music players to weather tools — relies on variables to track and update information instantly. Think of a variable as a labelled box: name it "score", put 10 inside, then swap it for 20 whenever you like. When you feel confident, try creating three variables — one for a name, one for an age, one for a favourite colour — and print them all.

The Magic Box Riddle

Imagine you have a box with a label on it that says 'score'. Right now, the box holds the number 0. Every time you answer a quiz question correctly, someone opens the box, takes out the old number, and puts in a new one — 1, then 2, then 3. The label never changes, but the contents keep updating. Here is the surprising part: almost every program you have ever used — from a game that tracks your lives to a weather app that shows today's temperature — relies on exactly this idea. That box with a changing value is called a variable.

What Is a Variable?

A is a named storage location in a computer's memory that holds a value. You give it a name (so you can refer to it) and a value (the data it currently stores). The value can be read, used in calculations, displayed on screen, or overwritten with a new value at any point during the program. Variables can hold different types of data. An integer (whole number) stores values like 5 or -3. A string stores text like 'Hello' or 'Layla'. A Boolean stores only True or False — useful for things like 'is the player alive?'. Declaring a variable means telling the program that the variable exists and giving it a starting value. In Python, you simply write the name, an equals sign, and the value: score = 0 player_name = 'Layla' game_over = False The equals sign here is called the . It does not mean 'is equal to' the way it does in maths — it means 'store this value in this variable'. Updating a variable means assigning a new value to the same name. The old value is replaced: score = 0 score = score + 10 # score is now 10 Notice the second line: the right-hand side is calculated first (0 + 10 = 10), then the result is stored back into score. This is the most common pattern in programming — using the old value to create the new value. Variable names should be descriptive so that anyone reading the code understands what is stored. Names like x or q give no clues; names like player_lives or current_temperature explain themselves instantly.

Worked example

A program counts how many goals a team has scored. Step 1 — Declare the variable with a starting value: goals = 0 Step 2 — The team scores. Update the variable: goals = goals + 1 # goals is now 1 Step 3 — The team scores again: goals = goals + 1 # goals is now 2 Step 4 — Display the result: print('Goals scored:', goals) # Output: Goals scored: 2 Because we used a variable, we only needed to write the print statement once. No matter how many goals are scored, the same line of code always displays the correct, up-to-date value.

Test Your Understanding

Try it yourself

Read each question carefully and choose the best answer. Think about what you learned before selecting.

1. Which of the following best describes a variable in programming?

2. What is the data type of the value stored by is_raining = True ?

3. A variable is declared as lives = 3 . After the line lives = lives - 1 runs, what value does lives hold?

4. Which variable name best follows good naming practice for a variable storing a player's current health?

5. Look at this code: temperature = 18 temperature = 22 print(temperature) What does the program output, and why?

Bring It Together

A variable is a named memory location — the name stays the same, but the value can change.
The assignment operator = stores a value into a variable; it does not mean mathematical equality.
Using the current value to calculate a new value (e.g. score = score + 1) is the most common way to update a variable.

1. A programmer writes: points = 50 points = points * 2 What is the value of points after both lines run?

🌱 Reflect

Think of a real program or game you know. Name one variable it probably uses and explain what type (integer, string, or Boolean) that variable's value would be and why.
