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. zGuido van Rossum , Mike Verdone , Mark Russell , Antoine Pitrou , Amaury Forgeot d'Arc , Benjamin Peterson BlockingIOErroropen open_codeIOBase RawIOBaseFileIOBytesIOStringIOBufferedIOBaseBufferedReaderBufferedWriterBufferedRWPairBufferedRandom TextIOBase TextIOWrapperUnsupportedOperationSEEK_SETSEEK_CURSEEK_ENDN)DEFAULT_BUFFER_SIZErrrrrrrr r r r IncrementalNewlineDecoderrioc@seZdZejjZdS)rN)__name__ __module__ __qualname___io_IOBase__doc__r r /usr/lib/python3.8/io.pyrHs) metaclassc@seZdZejjZdS)rN)rrrr _RawIOBaserr r r r!rKsc@seZdZejjZdS)r N)rrrr_BufferedIOBaserr r r r!r Nsc@seZdZejjZdS)rN)rrrr _TextIOBaserr r r r!rQs)_WindowsConsoleIO)%r __author____all__rabcrrrrrrrrr r r r rr OpenWrapperrrrrrABCMetarr#rr$r r%rregisterklassr& ImportErrorr r r r!sT$ @
