Why does name mangling not make private attributes completely inaccessible?

Because Python does not support private attributes

Because the mangled name can be accessed directly

Because the attribute is stored in the instance's __dict__

Because the attribute can be modified using the original name

A developer wants to programmatically list all instance variables of an object `obj`, including private ones, to verify that `__init__` set everything correctly. Which code snippet achieves this?

`list(type(obj).__dict__.keys())`

`[a for a in vars(type(obj)) if not callable(a)]`

`[a for a in dir(obj) if not a.startswith('_')]`

What happens when you try to access a private class variable from outside the class?

It returns the value of the variable

Given the class below, what is the output of the code? class Employee: company = 'TechCorp' def __init__(self, name): self.name = name e = Employee('Alice') print(e.company)

Error: 'Employee' object has no attribute 'company'
