Given a Python object, I can easily list which methods or attributes it has, directly in the interactive interpreter?

There are a few ways to display these attributes. Considering obj being the object you want to know more about (whether it is a declared variable or just a declared class).
The simplest and usual is the
dir:dir(obj)If you want to know not only the attributes, but their current values you can also use the
__dict__:obj.__dict__Finally, you always have the option to consult the help:
help(obj)

Just use the dir() function. An example of its use:
dir(objeto)

It is important that you know the python terminal. This will help your life a lot.
sudo apt-get install ipython.
You can install in virtualenv as well:
pip install ipython
Type ipython in the terminal.
With this you can import anything from python or your project’s class.
from people.models import Person
#digitando 'Person.' e apertando tab, você verá todos os atributos da classe Person. Veja a imagem do link
This will prevent you from doing things the "blind" and save a lot of time from your work.
