What does "bases ChatGetter" mean?
==================================
In Python, classes can base others. This is called `inheritance
<https://ddg.gg/python%20inheritance>`_. What it means is that
"if a class bases another, you can use the other's methods too".
For example, `Message <telethon.tl.custom.message.Message>` *bases*
`ChatGetter <telethon.tl.custom.chatgetter.ChatGetter>`. In turn,
`ChatGetter <telethon.tl.custom.chatgetter.ChatGetter>` defines
things like `obj.chat_id <telethon.tl.custom.chatgetter.ChatGetter>`.
So if you have a message, you can access that too:
.. code-block:: python
# ChatGetter has a chat_id property, and Message bases ChatGetter.
# Thus you can use ChatGetter properties and methods from Message
print(message.chat_id)
Telegram has a lot to offer, and inheritance helps the library reduce
boilerplate, so it's important to know this concept. For newcomers,
this may be a problem, so we explain what it means here in the FAQ.
