Other keyword argument) is passed through to the incremental decoder. Uses an incremental decoder to iteratively decode the input provided by iterdecode ( iterator, encoding, errors = 'strict', ** kwargs ) ¶ Therefore it does not support bytes-to-bytes encoders such asīase64_codec. This function requires that the codec accept text str objects Other keyword argument) is passed through to the incremental encoder. Uses an incremental encoder to iteratively encode the input provided by iterencode ( iterator, encoding, errors = 'strict', ** kwargs ) ¶ 'strict', which causes ValueError to be raised in case an encodingĮrror occurs. If file_encoding is not given, it defaults to data_encoding.Įrrors may be given to define the error handling.

Bytes read from the original file are decodedĪccording to file_encoding, and the result is encoded The original file is closedĭata written to the wrapped file is decoded according to the givenĭata_encoding and then written to the original file as bytes usingįile_encoding. Return a StreamRecoder instance, a wrapped version of file EncodedFile ( file, data_encoding, file_encoding = None, errors = 'strict' ) ¶ In case a search function cannot find a given encoding, it should returnĬhanged in version 3.11: The 'U' mode has been removed.

Look up the codec for the given encoding and return its incremental encoder Look up the codec for the given encoding and return its decoder function. Look up the codec for the given encoding and return its encoder function. These additional functions which use lookup() for the codec lookup: codecs. To simplify access to the various codec components, the module provides StreamWriter and StreamReader, respectively. Provide the interface defined by the base classes Stream writer and reader classes or factory functions. IncrementalEncoder and IncrementalDecoder, These have to provide the interface defined by the base classes Incremental encoder and decoder classes or factory functions. incrementalencoder ¶ incrementaldecoder ¶ The functions or methods are expected to work in a stateless mode. The encode() and decode() methods of Codec These must beįunctions or methods which have the same interface as The stateless encoding and decoding functions.

The full details for each codec can also be looked up directly: codecs. decode ( obj, encoding = 'utf-8', errors = 'strict' ) ¶ĭecodes obj using the codec registered for encoding.ĭefault error handler is 'strict' meaning that decoding errors raise ValueError (or a more codec specific subclass, such as Theĭefault error handler is 'strict' meaning that encoding errors raise encode ( obj, encoding = 'utf-8', errors = 'strict' ) ¶Įncodes obj using the codec registered for encoding.Įrrors may be given to set the desired error handling scheme. The module defines the following functions for encoding and decoding withĪny codec: codecs. Text encodings or with codecs that encode to Types, but some module features are restricted to be used specifically with Custom codecs may encode and decode between arbitrary Most standard codecsĪre text encodings, which encode text to bytes (andĭecode bytes to text), but there are also codecs provided that encode text to Manages the codec and error handling lookup process. This module defines base classes for standard Python codecs (encoders andĭecoders) and provides access to the internal Python codec registry, which Codecs - Codec registry and base classes ¶
