-"""The io module provides the Python interfaces to stream handling. The
-builtin open function is defined in this module.
-
-At the top of the I/O hierarchy is the abstract base class IOBase. It
-defines the basic interface to a stream. Note, however, that there is no
-separation between reading and writing to streams; implementations are
-allowed to raise an OSError if they do not support a given operation.
-
-Extending IOBase is RawIOBase which deals simply with the reading and
-writing of raw bytes to a stream. FileIO subclasses RawIOBase to provide
-an interface to OS files.
-
-BufferedIOBase deals with buffering on a raw byte stream (RawIOBase). Its
-subclasses, BufferedWriter, BufferedReader, and BufferedRWPair buffer
-streams that are readable, writable, and both respectively.
-BufferedRandom provides a buffered interface to random access
-streams. BytesIO is a simple stream of in-memory bytes.
-
-Another IOBase subclass, TextIOBase, deals with the encoding and decoding
-of streams into text. TextIOWrapper, which extends it, is a buffered text
-interface to a buffered raw stream (`BufferedIOBase`). Finally, StringIO
-is an in-memory stream for text.
-
-Argument names are not part of the specification, and only the arguments
-of open() are intended to be used as keyword arguments.
-
-data:
-
-DEFAULT_BUFFER_SIZE
-
- An int containing the default buffer size used by the module's buffered
- I/O classes. open() uses the file's blksize (as obtained by os.stat) if
- possible.
