Example:

```python
class A:
      def __init__(self):
          self._x = 3
          self.__x = 4

a = A()
print(a.__dict__)
```
will produce the output: ```{'_x': 3, '_A__x': 4}``` .

As you can see the "self.__x" field has the name "_A__x" which 
makes it "hidden", but not inaccessible.

But you can use external tools to check for misuse.
