How do I fill in the blanks to make the egg attribute strongly private and access it from outside of the class?

Question

I just don't understand how you do it.
class Test:
__egg = 7
t = Test()
print(t._Test_____)

Answer 1

@property is not answer 😂😂

Answer 2

to access the private attribute you prefix them with the undescore and name of their class. Like this:
print(t._Test__egg)
