The Correct Answer and Explanation is :
Correct Answers:
- True
- False
- False
Explanation:
1. A check button provides a single Boolean choice.
Correct Answer: True
A check button (often referred to as a checkbox) represents a Boolean choice. It can either be selected (checked) or not selected (unchecked). When checked, the value is typically represented as True, and when unchecked, it is False. This is a common feature in user interfaces for representing options that are independent of one another, such as toggling features or settings.
2. Selecting a check button will automatically unselect any other check buttons in its group.
Correct Answer: False
Check buttons operate independently of one another. Selecting one check button does not affect the state of other check buttons, even if they are part of the same group. This behavior contrasts with radio buttons, where selecting one automatically deselects others in the same group. Check buttons are often used when multiple selections are allowed simultaneously, such as choosing multiple toppings for a pizza.
3. Each check button in a Python program must have its own event handler function.
Correct Answer: False
While each check button can trigger a unique event handler, it is not mandatory for each to have a separate function. A single event handler function can manage multiple check buttons by identifying which one triggered the event. For example, in the Tkinter library, the state of a check button is tied to a variable, and the event handler can check the variable’s value to determine the button’s state. This approach simplifies code management, especially when handling many check buttons.
