Summary:

Booleans:

Two values: True and False. Used for logical comparisons.

Relational Operators:

Used for comparisons, e.g., equal to, not equal to, greater than, less than.

Popcorn Hack 1:

Example boolean expressions for age, average grade, and temperature checks.

Not Operator:

Flips a condition.

And Operator:

Combines two conditions.

Or Operator:

Returns True if at least one condition is true.

Conditionals:

Control program flow based on conditions. Include a condition, true block, and an optional false block.

Examples 2:

Illustrates conditional statements with elif.

Popcorn Hack 2:

Finds the highest score in a list.

Popcorn Hack 3:

A conditional program that checks age and driving conditions.
