359 “””
360 Open file and return a stream. Raise IOError upon failure.361
362 file is either a text or byte string giving the name (and the path363 if the file isn’t in the current working directory) of the file to364 be opened or an integer file descriptor of the file to be365 wrapped. (If a file descriptor is given, it is closed when the366 returned I/O object is closed, unless closefd is set to False.)367
368 mode is an optional string that specifies the mode in which the file369 is opened. It defaults to ‘r’ which means open for reading in text370 mode. Other common values are ‘w’ for writing (truncating the file if371 it already exists), ‘x’ for creating and writing to a new file, and372 ‘a’ for appending (which on some Unix systems, means that all writes373 append to the end of the file regardless of the current seek position).374 In text mode, if encoding is not specified the encoding used is platform375 dependent: locale.getpreferredencoding(False) is called to get the376 current locale encoding. (For reading and writing raw bytes use binary377 mode and leave encoding unspecified.) The available modes are:378
379 ========= ===============================================================380 Character Meaning381 ——— —————————————————————382 ‘r’ open for reading (default)383 ‘w’ open for writing, truncating the file first384 ‘x’ create a new file and open it for writing385 ‘a’ open for writing, appending to the end of the file if it exists386 ‘b’ binary mode387 ‘t’ text mode (default)388 ‘+’ open a disk file for updating (reading and writing)389 ‘U’ universal newline mode (deprecated)390 ========= ===============================================================391
392 The default mode is ‘rt’ (open for reading text). For binary random393 access, the mode ‘w+b’ opens and truncates the file to 0 bytes, while394 ‘r+b’ opens the file without truncation. The ‘x’ mode implies ‘w’ and395 raises an `FileExistsError` if the file already exists.396
397 Python distinguishes between files opened in binary and text modes,398 even when the underlying operating system doesn’t. Files opened in399 binary mode (appending ‘b’ to the mode argument) return contents as400 bytes objects without any decoding. In text mode (the default, or when401 ‘t’ is appended to the mode argument), the contents of the file are402 returned as strings, the bytes having been first decoded using a403 platform-dependent encoding or using the specified encoding if given.404
405 ‘U’ mode is deprecated and will raise an exception in future versions406 of Python. It has no effect in Python 3. Use newline to control407 universal newlines mode.408
409 buffering is an optional integer used to set the buffering policy.410 Pass 0 to switch buffering off (only allowed in binary mode), 1 to select411 line buffering (only usable in text mode), and an integer > 1 to indicate412 the size of a fixed-size chunk buffer. When no buffering argument is413 given, the default buffering policy works as follows:414
415 * Binary files are buffered in fixed-size chunks; the size of the buffer416 is chosen using a heuristic trying to determine the underlying device’s417 “block size” and falling back on `io.DEFAULT_BUFFER_SIZE`.418 On many systems, the buffer will typically be 4096 or 8192 bytes long.419
420 * “Interactive” text files (files for which isatty() returns True)421 use line buffering. Other text files use the policy described above422 for binary files.423
424 encoding is the name of the encoding used to decode or encode the425 file. This should only be used in text mode. The default encoding is426 platform dependent, but any encoding supported by Python can be427 passed. See the codecs module for the list of supported encodings.428
429 errors is an optional string that specifies how encoding errors are to430 be handled—this argument should not be used in binary mode. Pass431 ‘strict’ to raise a ValueError exception if there is an encoding error432 (the default of None has the same effect), or pass ‘ignore’ to ignore433 errors. (Note that ignoring encoding errors can lead to data loss.)434 See the documentation for codecs.register or run ‘help(codecs.Codec)’435 for a list of the permitted encoding error strings.436
437 newline controls how universal newlines works (it only applies to text438 mode). It can be None, ”, ‘\n’, ‘\r’, and ‘\r\n’. It works as439 follows:440
441 * On input, if newline is None, universal newlines mode is442 enabled. Lines in the input can end in ‘\n’, ‘\r’, or ‘\r\n’, and443 these are translated into ‘\n’ before being returned to the444 caller. If it is ”, universal newline mode is enabled, but line445 endings are returned to the caller untranslated. If it has any of446 the other legal values, input lines are only terminated by the given447 string, and the line ending is returned to the caller untranslated.448
449 * On output, if newline is None, any ‘\n’ characters written are450 translated to the system default line separator, os.linesep. If451 newline is ” or ‘\n’, no translation takes place. If newline is any452 of the other legal values, any ‘\n’ characters written are translated453 to the given string.454
455 If closefd is False, the underlying file descriptor will be kept open456 when the file is closed. This does not work when a file name is given457 and must be True in that case.458
459 A custom opener can be used by passing a callable as *opener*. The460 underlying file descriptor for the file object is then obtained by461 calling *opener* with (*file*, *flags*). *opener* must return an open462 file descriptor (passing os.open as *opener* results in functionality463 similar to passing None).464
465 open() returns a file object whose type depends on the mode, and466 through which the standard file operations such as reading and writing467 are performed. When open() is used to open a file in a text mode (‘w’,468 ‘r’, ‘wt’, ‘rt’, etc.), it returns a TextIOWrapper. When used to open469 a file in a binary mode, the returned class varies: in read binary470 mode, it returns a BufferedReader; in write binary and append binary471 modes, it returns a BufferedWriter, and in read/write mode, it returns472 a BufferedRandom.473
474 It is also possible to use a string or bytearray as a file for both475 reading and writing. For strings StringIO can be used like a file476 opened in a text mode, and for bytes a BytesIO can be used like a file477 opened in a binary mode.478 “””
