I know one can access information about python3 classes and methods
(e.g. list the methods in a class, show the parameters for a method,
etc.) but I always forget how to do it.

Can someone enlighten me please, plus tell me where it is documented
so that I can bookmark it and not need to ask again.

You can say (in the interactive console), with "int" as an
example of a class and "to_bytes" as an example of a method
(each line is a separate input):

int
int.to_bytes
(1).to_bytes.__qualname__
type( int )
type( int.to_bytes )
type( 1 )
type( (1).to_bytes )
dir( int )
dir( int.to_bytes )
help( int )
help( int.to_bytes )
help( 1 )
help( (1).to_bytes )
help() # and then later "quit" to quit help mode

. Some IDEs give information or help about functions etc.
after pressing some key, like Ctrl-Space or something.

On Windows, the program group "Python" often has entries
"Python 3.14 Manuals" and "Python 3.14 Module Docs".

You can also find the Manuals in the Web as Web pages;
I prefer the PDF manuals, but these now have been discontinued.

You can ask any AI chatbot, "Tell me about the Python class int!",
"What's the Web address of the Python documentation!" etc.

The “help()” function?

I refer to <https://docs.python.org/3/library/> so often that I don’t
even need to bookmark it: it’s in my browser’s autocomplete.
