+"Open file and return a stream.  Raise IOError upon failure.\n"

+"file is either a text or byte string giving the name (and the path\n"
+"if the file isn\'t in the current working directory) of the file to\n"
+"be opened or an integer file descriptor of the file to be\n"
+"wrapped. (If a file descriptor is given, it is closed when the\n"
+"returned I/O object is closed, unless closefd is set to False.)\n"
+"\n"
+"mode is an optional string that specifies the mode in which the file\n"
+"is opened. It defaults to \'r\' which means open for reading in text\n"
+"mode.  Other common values are \'w\' for writing (truncating the file if\n"
+"it already exists), \'x\' for creating and writing to a new file, and\n"
+"\'a\' for appending (which on some Unix systems, means that all writes\n"
+"append to the end of the file regardless of the current seek position).\n"
+"In text mode, if encoding is not specified the encoding used is platform\n"
+"dependent: locale.getpreferredencoding(False) is called to get the\n"
+"current locale encoding. (For reading and writing raw bytes use binary\n"
+"mode and leave encoding unspecified.) The available modes are:\n"
+"\n"
+"========= ===============================================================\n"
+"Character Meaning\n"
+"--------- ---------------------------------------------------------------\n"
+"\'r\'       open for reading (default)\n"
+"\'w\'       open for writing, truncating the file first\n"
+"\'x\'       create a new file and open it for writing\n"
+"\'a\'       open for writing, appending to the end of the file if it exists\n"
+"\'b\'       binary mode\n"
+"\'t\'       text mode (default)\n"
+"\'+\'       open a disk file for updating (reading and writing)\n"
+"\'U\'       universal newline mode (deprecated)\n"
+"========= ===============================================================\n"
+"\n"
+"The default mode is \'rt\' (open for reading text). For binary random\n"
+"access, the mode \'w+b\' opens and truncates the file to 0 bytes, while\n"
+"\'r+b\' opens the file without truncation. The \'x\' mode implies \'w\' and\n"
+"raises an `FileExistsError` if the file already exists.\n"
+"\n"
+"Python distinguishes between files opened in binary and text modes,\n"
+"even when the underlying operating system doesn\'t. Files opened in\n"
+"binary mode (appending \'b\' to the mode argument) return contents as\n"
+"bytes objects without any decoding. In text mode (the default, or when\n"
+"\'t\' is appended to the mode argument), the contents of the file are\n"
+"returned as strings, the bytes having been first decoded using a\n"
+"platform-dependent encoding or using the specified encoding if given.\n"
+"\n"
+"\'U\' mode is deprecated and will raise an exception in future versions\n"
+"of Python.  It has no effect in Python 3.  Use newline to control\n"
+"universal newlines mode.\n"
+"\n"
+"buffering is an optional integer used to set the buffering policy.\n"
+"Pass 0 to switch buffering off (only allowed in binary mode), 1 to select\n"
+"line buffering (only usable in text mode), and an integer > 1 to indicate\n"
+"the size of a fixed-size chunk buffer.  When no buffering argument is\n"
+"given, the default buffering policy works as follows:\n"
+"\n"
+"* Binary files are buffered in fixed-size chunks; the size of the buffer\n"
+"  is chosen using a heuristic trying to determine the underlying device\'s\n"
+"  \"block size\" and falling back on `io.DEFAULT_BUFFER_SIZE`.\n"
+"  On many systems, the buffer will typically be 4096 or 8192 bytes long.\n"
+"\n"
+"* \"Interactive\" text files (files for which isatty() returns True)\n"
+"  use line buffering.  Other text files use the policy described above\n"
+"  for binary files.\n"
+"\n"
+"encoding is the name of the encoding used to decode or encode the\n"
+"file. This should only be used in text mode. The default encoding is\n"
+"platform dependent, but any encoding supported by Python can be\n"
+"passed.  See the codecs module for the list of supported encodings.\n"
+"\n"
+"errors is an optional string that specifies how encoding errors are to\n"
+"be handled---this argument should not be used in binary mode. Pass\n"
+"\'strict\' to raise a ValueError exception if there is an encoding error\n"
+"(the default of None has the same effect), or pass \'ignore\' to ignore\n"
+"errors. (Note that ignoring encoding errors can lead to data loss.)\n"
+"See the documentation for codecs.register or run \'help(codecs.Codec)\'\n"
+"for a list of the permitted encoding error strings.\n"
+"\n"
+"newline controls how universal newlines works (it only applies to text\n"
+"mode). It can be None, \'\', \'\\n\', \'\\r\', and \'\\r\\n\'.  It works as\n"
+"follows:\n"
+"\n"
+"* On input, if newline is None, universal newlines mode is\n"
+"  enabled. Lines in the input can end in \'\\n\', \'\\r\', or \'\\r\\n\', and\n"
+"  these are translated into \'\\n\' before being returned to the\n"
+"  caller. If it is \'\', universal newline mode is enabled, but line\n"
+"  endings are returned to the caller untranslated. If it has any of\n"
+"  the other legal values, input lines are only terminated by the given\n"
+"  string, and the line ending is returned to the caller untranslated.\n"
+"\n"
+"* On output, if newline is None, any \'\\n\' characters written are\n"
+"  translated to the system default line separator, os.linesep. If\n"
+"  newline is \'\' or \'\\n\', no translation takes place. If newline is any\n"
+"  of the other legal values, any \'\\n\' characters written are translated\n"
+"  to the given string.\n"
+"\n"
+"If closefd is False, the underlying file descriptor will be kept open\n"
+"when the file is closed. This does not work when a file name is given\n"
+"and must be True in that case.\n"
+"\n"
+"A custom opener can be used by passing a callable as *opener*. The\n"
+"underlying file descriptor for the file object is then obtained by\n"
+"calling *opener* with (*file*, *flags*). *opener* must return an open\n"
+"file descriptor (passing os.open as *opener* results in functionality\n"
+"similar to passing None).\n"
+"\n"
+"open() returns a file object whose type depends on the mode, and\n"
+"through which the standard file operations such as reading and writing\n"
+"are performed. When open() is used to open a file in a text mode (\'w\',\n"
+"\'r\', \'wt\', \'rt\', etc.), it returns a TextIOWrapper. When used to open\n"
+"a file in a binary mode, the returned class varies: in read binary\n"
+"mode, it returns a BufferedReader; in write binary and append binary\n"
+"modes, it returns a BufferedWriter, and in read/write mode, it returns\n"
+"a BufferedRandom.\n"
+"\n"
+"It is also possible to use a string or bytearray as a file for both\n"
+"reading and writing. For strings StringIO can be used like a file\n"
+"opened in a text mode, and for bytes a BytesIO can be used like a file\n"
+"opened in a binary mode.");
