Index of "The Python Library Reference, Release 3.9.0a3"
But none of those is the documentation for read(), they're just places
that refer to read().
There's no read() function. What you're referring to are the 'read'
methods of various classes.
If you open a file in text mode, you'll get an instance of
TextIOWrapper, which inherits .read from TextIOBase.
If you open a file in binary mode, you'll get an instance of
BufferedReader, which has a .read method.
Multiple classes, each with its own 'read' method.
sys.stdin is an instance of TextIOWrapper, so for that you should look
at the methods of TextIOWrapper.
