question 37

Multiple Choice

Consider the following code which would set the hour of a Time object to an invalid value. wake_up._hour = 100
Which of the following statements is false?

• A) Rather than _hour, we can name the attribute __hour with two leading underscores. This convention indicates that __hour is "private" and should not be accessible to the class's xe "client of a class"clients.
• B) To help prevent clients from accessing "private" attributes, Python renames them by preceding the attribute name with _ClassName, as in _Time__hour. This is called xe "name mangling"name mangling.
• C) If you try to assign to __hour, as in
• Wake_up.__hour = 100
• Python raises a ValueError, indicating that the class does not have an __hour attribute.
• D) IPython does not show attributes with one or two leading underscores when you try to auto-complete an expression like
• Wake_up.
• By pressing Tab. Only attributes that are part of the wake_up object's "public" interface are displayed in the IPython auto-completion list.
