The easiest way to create a text stream is with open(), optionally specifying an encoding:

https://docs.python.org/3.11/library/io.html?highlight=io#binary-i-o - 

The easiest way to create a binary stream is with open() with 'b' in the mode string:

For both of these cases, the markup for the open() is :meth:`open()` but it links to the builtins open(), which I see is an alias of io.open() so maybe it doesn't matter?
Another question is why do only these two instances use :meth: while the other instances in the file use :func: (some refer directly to builtins open() so its understandable, but not all instances)
I'm wondering if the above two should be left alone or changed to :meth:`~io.open` or even :func:`open`
