When no buffering argument is given, the default buffering policy works as follows: * Binary files are buffered in fixed-size chunks; the size of the buffer is chosen using a heuristic trying to determine the underlying device's "block size" and falling back on `io.DEFAULT_BUFFER_SIZE`. On many systems, the buffer will typically be 4096 or 8192 bytes long. * "Interactive" text files (files for which isatty() returns True) use line buffering. Other text files use the policy described above for binary files. encoding is the str name of the encoding used to decode or encode the file. This should only be used in text mode. The default encoding is platform dependent, but any encoding supported by Python can be passed. See the codecs module for the list of supported encodings. errors is an optional string that specifies how encoding errors are to be handled---this argument should not be used in binary mode. Pass 'strict' to raise a ValueError exception if there is an encoding error (the default of None has the same effect), or pass 'ignore' to ignore errors. (Note that ignoring encoding errors can lead to data loss.) See the documentation for codecs.register for a list of the permitted encoding error strings. newline is a string controlling how universal newlines works (it only applies to text mode). It can be None, '', '\n', '\r', and '\r\n'. It works as follows: * On input, if newline is None, universal newlines mode is enabled. Lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n' before being returned to the caller. If it is '', universal newline mode is enabled, but line endings are returned to the caller untranslated. If it has any of the other legal values, input lines are only terminated by the given string, and the line ending is returned to the caller untranslated. * On output, if newline is None, any '\n' characters written are translated to the system default line separator, os.linesep. If newline is '', no translation takes place. If newline is any of the other legal values, any '\n' characters written are translated to the given string. closedfd is a bool. If closefd is False, the underlying file descriptor will be kept open when the file is closed. This does not work when a file name is given and must be True in that case. The newly created file is non-inheritable. A custom opener can be used by passing a callable as *opener*. The underlying file descriptor for the file object is then obtained by calling *opener* with (*file*, *flags*). *opener* must return an open file descriptor (passing os.open as *opener* results in functionality similar to passing None). open() returns a file object whose type depends on the mode, and through which the standard file operations such as reading and writing are performed. When open() is used to open a file in a text mode ('w', 'r', 'wt', 'rt', etc.), it returns a TextIOWrapper. When used to open a file in a binary mode, the returned class varies: in read binary mode, it returns a BufferedReader; in write binary and append binary modes, it returns a BufferedWriter, and in read/write mode, it returns a BufferedRandom. It is also possible to use a string or bytearray as a file for both reading and writing. For strings StringIO can be used like a file opened in a text mode, and for bytes a BytesIO can be used like a file opened in a binary mode. zinvalid file: %rzinvalid mode: %rzinvalid buffering: %rNinvalid encoding: %rinvalid errors: %rzaxrwb+txrwa+tbz'can't have text and binary mode at oncer z)can't have read/write/append mode at oncez/must have exactly one of read/write/append modez-binary mode doesn't take an encoding argumentz+binary mode doesn't take an errors argumentz+binary mode doesn't take a newline argumentrzaline buffering (buffering=1) isn't supported in binary mode, the default buffer size will be usedr )openerFTzinvalid buffering sizezcan't have unbuffered text I/Ozunknown mode: %r) isinstanceintosfspathstrbytes TypeErrorsetlen ValueErrorrrRuntimeWarningFileIOisattyDEFAULT_BUFFER_SIZEfstatfileno st_blksizeOSErrorAttributeErrorBufferedRandomBufferedWriterBufferedReaderr TextIOWrappermodeclose)filerB bufferingrerrorsnewlineclosefdr)modescreatingreadingwriting appendingupdatingtextbinaryrrawresultline_bufferingbsbuffers ropenrVLszn dC yy dS%- .*T122 dC *T122 i %/);<<Jx$=.9:: *VS"9,v566 IE s9~TSZ!7+d233e|HUlGUlGu Ie|H %Y]szz|I!N q=+I #XXcjjl+666 "I q=56 6 > => > #C3F I#C3F #C3F/$67 7 M *VXvwO  5^,  6  s=5+K9!-K$ K9/AK9?$K9$K63K95K66K99L cPddl}|jdtdt|dS)azOpens the provided file with mode ``'rb'``.

This class provides dummy implementations for many methods that derived classes can override selectively; the default implementations represent a file that cannot be read, written or seeked. Even though IOBase does not declare read or write because their signatures will vary, implementations and clients should consider those methods part of the interface. Also, implementations may raise UnsupportedOperation when operations they do not support are called. The basic type used for binary data read from or written to a file is bytes. Other bytes-like objects are accepted as method arguments too. Text I/O classes work with str data. Note that calling any method (even inquiries) on a closed stream is undefined. Implementations may raise OSError in this case. IOBase (and its subclasses) support the iterator protocol, meaning that an IOBase object can be iterated over yielding the lines in a stream. IOBase also supports the :keyword:`with` statement. In this example, fp is closed after the suite of the with statement is complete: with open('spam.txt', 'r') as fp: fp.write('Spam and eggs!') cLt|jjd|d)z@Internal: raise an OSError exception for unsupported operations..z() not supported)r\ __class__r])selfnames r _unsupportedzIOBase._unsupported]s&"$(NN$;$;T$CD Drc&|jdy)a$Change stream position.

It defaults to locale.getencoding(). errors determines the strictness of encoding and decoding (see the codecs.register) and defaults to "strict". newline can be None, '', '\n', '\r', or '\r\n'. It controls the handling of line endings. If it is None, universal newlines is enabled. With this enabled, on input, the lines endings '\n', '\r', or '\r\n' are translated to '\n' before being returned to the caller. Conversely, on output, '\n' is translated to the system default line separator, os.linesep. If newline is any other of its legal values, that newline becomes the newline when the file is read and it is returned untranslated. On output, '\n' is converted to the newline. If line_buffering is True, a call to flush is implied when a call to write contains a newline character. iNc`|j|t|}|dk(r|j}t|tst d|zt j|jsd}t||z|d}n9t|tst d|ztrt j|||_ d|_ d|_d|_|j j#x|_|_t)|j d|_|j-|||||y) NrrzG%r is not a text encoding; use codecs.open() to handle arbitrary codecsr r r(rr)_check_newliner_get_locale_encodingr+r/r4rlookup_is_text_encoding LookupError _CHECK_ERRORS lookup_errorr _decoded_chars_decoded_chars_used _snapshotrUrr_tellingr _has_read1 _configure)rfrUrrFrGrS write_throughrs rrzTextIOWrapper.__init__s  G$ * x 002H(C(3h>? ?}}X&88BCcHn- - >Ffc* !5!>??##F+  #$ )-)=)=)??!$++w7 &'&  7rcz|'t|tstdt||dvrt d|y)Nzillegal newline type: )Nr(rrrzillegal newline value: )r+r/r1typer4)rfrGs rrzTextIOWrapper._check_newlines?  z'3'?$w-IJ J 8 8GEF F 9rc||_||_d|_d|_d|_| |_|du|_||_|dk7|_|xstj|_ ||_ ||_ |jrR|jrA|j j#}|dk7r! |j%j'dyyyy#t($rYywxYw)Nr(r) _encoding_errors_encoder_decoder _b2cratio_readuniversal_readtranslate_readnl_writetranslater-linesep_writenl_line_buffering_write_throughrrrUrq _get_encoderrr)rfrrFrGrSrpositions rrzTextIOWrapper._configures!
