Exam-style question
Try this first
The Boolean variables `has_ticket` and `is_member` contain either True or False. Write a Python 3 Boolean expression that is True if a person has a ticket and is a member, and False otherwise. Explain why the expression works. Then state the result when `has_ticket` is True and `is_member` is False.
Model answer
What a good answer should say
- The expression is `has_ticket and is_member`.
- AND gives True only when both operands are True.
- When `has_ticket` is True and `is_member` is False, the expression evaluates to False.
Explanation
Why this works
The required condition contains two requirements that must both be satisfied, so AND is appropriate. Because one of the values is False in the stated case, the overall result is False.
