Logical Operators

Learning Objectives Define the three main logical operators: `and`, `or`, and `not`. Predict the True/False outcome of a conditional statement using the `and` operator. Predict the True/False outcome of a conditional statement using the `or` operator. Use the `not` operator to reverse a Boolean value. Write a simple Python `if` statement that combines two conditions using a logical operator. Want to get into the secret treehouse? 🌳 You need to know the password AND be wearing the secret color. How does a computer check if both things are true at once? In this lesson, you'll learn about special keywords called Logical Operators. These operators (`and`, `or`, `not`) let us combine simple True/False questions into more powerful ones, helping our programs make smarter decis...

TermDefinitionExample Logical OperatorA special word used to connect or change True/False values (Booleans). The main ones are `and`, `or`, and `not`.In `(score > 10) and (level == 5)`, the word `and` is the logical operator. BooleanA data type that can only have one of two values: `True` or `False`.The variable `is_sunny = True` holds a Boolean value. andA logical operator that checks if BOTH conditions are `True`. The whole expression is only `True` if every part is `True`.`True and True` results in `True`. But `True and False` results in `False`. orA logical operator that checks if AT LEAST ONE condition is `True`. The whole expression is `True` if one part (or both) is `True`.`True or False` results in `True`. Only `False or False` results in `False`. notA logical operator that fli...

The 'and' Rule (The Strict Parent) condition1 and condition2 Use `and` when you need multiple things to be true at the same time. Think of it as a strict rule: you must do this AND that. If even one part is False, the whole thing is False. The 'or' Rule (The Easy-Going Friend) condition1 or condition2 Use `or` when you only need one of several things to be true. Think of it as having a choice: you can do this OR that. As long as one part is True, the whole thing is True. The 'not' Rule (The Opposite Day Rule) not condition Use `not` to check if something is False. It flips the value of the condition that follows it. It's useful for checking when something *isn't* happening.
