Comparisons

Bigger, smaller, or equal?

Learn how to compare values in Python — is this bigger than that? Are they equal? Let Python judge!

📖

What we are learning

Comparison operators let Python compare two values. Is 5 bigger than 3? Is your score equal to the high score? Comparisons always produce a boolean: True or False. You can use them in if statements to make decisions.

💡 Think of it like this:

Think of a balance scale. You put one thing on each side and the scale tells you which is heavier. Comparison operators do the same thing — they compare two values and tell you the result.

Why it matters

Comparisons are how programs check rules. Is the password long enough? Is the temperature too hot? Is the player close enough to the goal? All of these use comparisons.

Where you see this in real life:

✓Thermostats check if the temperature is above or below a target
✓Games check if your score is greater than the high score
✓Elevators check if the current floor equals the requested floor

🎯

By the end, you can:

1.Use ==, !=, <, >, <=, >= to compare values
2.Combine comparisons with and, or, not
3.Use comparisons in if statements

Is your age greater than 10? Is it less than 15? Is it exactly 12? Write down the answers as True or False.

Fun Fact!

In Python, == checks if two things are equal, but = assigns a value. Mixing them up is the #1 beginner mistake!

⚖️ Comparing Values

Comparison operators let Python compare two values. The result is always a boolean:Trueor False.

🔧 Comparison Operators

Equal to

5 == 5 → True

Not equal

5 != 3 → True

Greater than

10 > 5 → True

Less than

3 < 7 → True

Greater or equal

5 >= 5 → True

Less or equal

3 <= 5 → True

⚠️ == vs =

This is the #1 beginner mistake! = and == are different!

= Assignment

Stores a value in a variable

x = 5 # x now holds 5

== Comparison

Checks if two values are equal

x == 5 # True if x is 5

🎯 Comparisons in if Statements

Comparisons are most useful inside if statements!

Try this: write a program that checks if a variable 'age' is greater than or equal to 13. Print 'Teenager!' if it is.
