Hello dear PYTHON developers
i have found python bug probably it's bug
when i create private variable class i can call in the interpreter
i m show here

class MyClass:
... __private_var = "it's text very important"
...
c = MyClass()
dir(c)
['_MyClass__private_var', 'class', 'delattr', 'dict', 'dir', 'doc', 'eq', 'format', 'ge', 'getattribute', 'gt', 'hash', 'init', 'init_subclass', 'le', 'lt', 'module', 'ne', 'new', 'reduce', 'reduce_ex', 'repr', 'setattr', 'sizeof', 'str', 'subclasshook', 'weakref']
you can see in list first item and i can call this variable isnt private
c._MyClass__private_var
"it's text very important"

it's probably bug
