Documentation of hidden class methods in Sphinx

Question

Python

I have a class:

#module main.py:

class A:
    a = 1
    """Переменная a"""

    b = 2
    """Переменная B"""

    def _B(self):
        """Функция _B"""

I do autodocumentation on Sphinx and write to the main file

.. automodule: main
:members:

In this case, it prints only the documentation for the a and b members of the class. If you write

.. automodule: main
:members: _B

then it will output method _B but not properties a and b. How can I display all hidden methods and properties of a class?
