Classes

BytesIO

Buffered I/O implementation using an in-memory bytes buffer.

close(self, /)

  Disable all I/O operations.

detach(self, /)

  Disconnect this buffer from its underlying raw stream and return it.

  After the raw stream has been detached, the buffer is in an unusable
  state.

fileno(self, /)

  Returns underlying file descriptor if one exists.

  OSError is raised if the IO object does not use a file descriptor.

flush(self, /)

  Does nothing.

getbuffer(self, /)

  Get a read-write view over the contents of the BytesIO object.

getvalue(self, /)

  Retrieve the entire contents of the BytesIO object.

isatty(self, /)

  Always returns False.

  BytesIO objects are not connected to a TTY-like device.

read(self, size=-1, /)

  Read at most size bytes, returned as a bytes object.

  If the size argument is negative, read until EOF is reached.
  Return an empty bytes object at EOF.

read1(self, size=-1, /)

  Read at most size bytes, returned as a bytes object.

  If the size argument is negative or omitted, read until EOF is reached.
  Return an empty bytes object at EOF.

readable(self, /)

  Returns True if the IO object can be read.

readinto(self, buffer, /)

  Read bytes into buffer.

  Returns number of bytes read (0 for EOF), or None if the object
  is set not to block and has no data to read.

readinto1(self, buffer, /)

readline(self, size=-1, /)

  Next line from the file, as a bytes object.

  Retain newline.  A non-negative size argument limits the maximum
  number of bytes to return (an incomplete line may be returned then).
  Return an empty bytes object at EOF.

readlines(self, size=None, /)

  List of bytes objects, each a line from the file.

  Call readline() repeatedly and return a list of the lines so read.
  The optional size argument, if given, is an approximate bound on the
  total number of bytes in the lines returned.

seek(self, pos, whence=0, /)

  Change stream position.

  Seek to byte offset pos relative to position indicated by whence:
       0  Start of stream (the default).  pos should be >= 0;
       1  Current position - pos may be negative;
       2  End of stream - pos usually negative.
  Returns the new absolute position.

seekable(self, /)

  Returns True if the IO object can be seeked.

tell(self, /)

  Current file position, an integer.

truncate(self, size=None, /)

  Truncate the file to at most size bytes.

  Size defaults to the current file position, as returned by tell().
  The current file position is unchanged.  Returns the new size.

writable(self, /)

  Returns True if the IO object can be written.

write(self, b, /)

  Write bytes to file.

  Return the number of bytes written.

writelines(self, lines, /)

  Write lines to the file.

  Note that newlines are not added.  lines can be any iterable object
  producing bytes-like objects. This is equivalent to calling write() for
  each element.

closed = <attribute 'closed' of '_io.BytesIO' objects>
  True if the file is closed.

ConversionError

with_traceback(...)

  Exception.with_traceback(tb) --
      set self.__traceback__ to tb and return self.

args = <attribute 'args' of 'BaseException' objects>

Error

Exception class for this module. Use:

    except xdrlib.Error as var:
        # var has the Error instance for the exception

    Public ivars:
        msg -- contains the message

with_traceback(...)

  Exception.with_traceback(tb) --
      set self.__traceback__ to tb and return self.

args = <attribute 'args' of 'BaseException' objects>

Functions

raise_conversion_error

raise_conversion_error(function)

   Wrap any raised struct.errors in a ConversionError.

wraps

wraps(wrapped, assigned=('__module__', '__name__', '__qualname__', '__doc__', '__annotations__'), updated=('__dict__',))

  Decorator factory to apply update_wrapper() to a wrapper function

         Returns a decorator that invokes update_wrapper() with the decorated
         function as the wrapper argument and the arguments to wraps() as the
         remaining arguments. Default arguments are as for update_wrapper().
         This is a convenience function to simplify applying partial() to
         update_wrapper().
