BufferedIOBase

class io.BufferedIOBase

Bases: _BufferedIOBase, IOBase

Base class for buffered IO objects.

The main difference with RawIOBase is that the read() method supports omitting the size argument, and does not have a default implementation that defers to readinto().

In addition, read(), readinto() and write() may raise BlockingIOError if the underlying raw stream is in non-blocking mode and not ready; unlike their raw counterparts, they will never return None.

A typical implementation should not inherit from a RawIOBase implementation, but wrap one.
