+"Open file and return a stream. Raise IOError upon failure.\n"
+"\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), and 'a' for appending (which on some Unix systems,\n"
+"means that all writes append to the end of the file regardless of the\n"
+"current seek position). In text mode, if encoding is not specified the\n"
+"encoding used is platform dependent. (For reading and writing raw\n"
+"bytes use binary mode and leave encoding unspecified.) The available\n"
+"modes are:\n"
+"\n"
+"========= ===============================================================\n"
+"Character Meaning\n"
+"--------- ---------------------------------------------------------------\n"
+"'r' open for reading (default)\n"
+"'w' open for writing, truncating the file first\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 (for backwards compatibility; unneeded\n"
+" for new code)\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.\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"
+"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 for a list of the permitted\n"
+"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 '', no translation takes place. If newline is any of the\n"
+" other legal values, any '\\n' characters written are translated to\n"
+" 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"
+"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.\n"
