![]() That derived classes can override selectively the default This class provides empty abstract implementations for many methods The abstract base class for all I/O classes. The following table summarizes the ABCs provided by the io module: Open() are intended to be used as keyword arguments. StringIO is an in-memory stream for text.Īrgument names are not part of the specification, and only the arguments of Interface to a buffered raw stream ( BufferedIOBase). TextIOWrapper, which extends TextIOBase, is a buffered text Streams whose bytes represent text, and handles encoding and decoding to andįrom strings. BufferedRandom provides a buffered interface to seekable streams.Īnother BufferedIOBase subclass, BytesIO, is a stream of Its subclasses,īufferedWriter, BufferedReader, and BufferedRWPairīuffer raw binary streams that are writable, readable, and both readable and writable, It deals withīuffering on a raw binary stream ( RawIOBase). To provide an interface to files in the machine’s file system. It deals with the readingĪnd writing of bytes to a stream. To raise UnsupportedOperation if they do not support a given operation. Separation between reading and writing to streams implementations are allowed Itĭefines the basic interface to a stream. ForĮxample, BufferedIOBase provides unoptimized implementations ofĪt the top of the I/O hierarchy is the abstract base class IOBase. ![]() Methods in order to help implementation of concrete stream classes. The abstract base classes also provide default implementations of some Overriding the behavior is intended forĪdditional validation or preprocessing of the file. Str and an absolute path, open_code(path) should always behave ![]() The behavior of this function may be overridden by an earlier call to the Path should be a str and an absolute path. When the intent is to treat the contents as executable code. The mode and flagsĪrguments may have been modified or inferred from the original call. This function raises an auditing event open withĪrguments path, mode and flags. This is an alias for the builtin open() function. open ( file, mode = 'r', buffering = - 1, encoding = None, errors = None, newline = None, closefd = True, opener = None ) ¶ open() uses the file’s blksize (as obtained by DEFAULT_BUFFER_SIZE ¶Īn int containing the default buffer size used by the module’s buffered I/OĬlasses. Please consider using UTF-8 by default (i.e. TextIOWrapper and passes encoding=None as a parameter, youĬan use text_encoding() so that callers of the API will emit anĮncodingWarning if they don’t pass an encoding. If you are providing an API that uses open() or PYTHONWARNDEFAULTENCODING environment variable, which willĮmit an EncodingWarning when the default encoding is used. The -X warn_default_encoding command line option or set the To find where the default locale encoding is used, you can enable ◾Dimensions (B x H x D in mm) 255 x 160 x 110 ew Weight 1.New in version 3.10: See PEP 597 for more details. ◾ Requires 6x AA batteries (not included) ◾Optional battery or 230V socket via AC adapter (adapter included) ◾Stereo headphone socket 3, 5 mm jack terStereo Line-Out socket 3.5 mm jack ◾Stereo line-in socket for iPod / MP3 playback 3.5 mm jack ◾2 alarm timer (DAB + / FM / Internet radio, or alarm tone) ◾Play your music collection from your computer ◾Receipt of radio stations nationwide and worldwide ◾Remote control via free app Technical data: ◾Built-in charger charges NiMH AA cells (6 x AA) ◾2 independent alarm functions WeSleep -Timer ◾MP3 / WMA / FLAC and many more formats FormatePodcasts ◾Spotify, TIDAL, Deezer, Amazon Prime Music With two alarm functions, the iStream 3 is also an attractive bedside radio.
