Python in a Nutshell

Name

EncodedFile

Synopsis

EncodedFile(file,datacodec,filecodec=None,errors=’strict')

Wraps the file-like object file, returning another file-like object ef that implicitly and transparently applies the given encodings to all data read from or written to the file. When you write a string s to ef, ef first decodes s with the codec named by datacodec, then encodes the result with the codec named by filecodec, and lastly writes it to file. When you read a string, ef applies filecodec first, then datacodec. When filecodec is None, ef uses datacodec for both steps in either direction.

For example, if you want to write strings that are encoded in latin-1 to sys.stdout and have the strings come out in utf-8, use the following:

import sys, codecs
sys.stdout = codecs.EncodedFile(sys.stdout,'latin-1',
                                                     'utf-8')
