| |
| Open file and return a stream. Raise OSError upon failure. |
| |
| file is either a text or byte string giving the name (and the path |
| if the file isn't in the current working directory) of the file to |
| be opened or an integer file descriptor of the file to be |
| wrapped. (If a file descriptor is given, it is closed when the |
| returned I/O object is closed, unless closefd is set to False.) |
| |
| mode is an optional string that specifies the mode in which the file |
| is opened. It defaults to 'r' which means open for reading in text |
| mode. Other common values are 'w' for writing (truncating the file if |
| it already exists), 'x' for creating and writing to a new file, and |
| 'a' for appending (which on some Unix systems, means that all writes |
| append to the end of the file regardless of the current seek position). |
| In text mode, if encoding is not specified the encoding used is platform |
| dependent: locale.getencoding() is called to get the current locale encoding. |
| (For reading and writing raw bytes use binary mode and leave encoding |
| unspecified.) The available modes are: |
| |
| ========= =============================================================== |
| Character Meaning |
| --------- --------------------------------------------------------------- |
| 'r' open for reading (default) |
| 'w' open for writing, truncating the file first |
| 'x' create a new file and open it for writing |
| 'a' open for writing, appending to the end of the file if it exists |
| 'b' binary mode |
| 't' text mode (default) |
| '+' open a disk file for updating (reading and writing) |
| ========= =============================================================== |
| |
| The default mode is 'rt' (open for reading text). For binary random |
| access, the mode 'w+b' opens and truncates the file to 0 bytes, while |
| 'r+b' opens the file without truncation. The 'x' mode implies 'w' and |
| raises an `FileExistsError` if the file already exists. |
| |
| Python distinguishes between files opened in binary and text modes, |
| even when the underlying operating system doesn't. Files opened in |
| binary mode (appending 'b' to the mode argument) return contents as |
| bytes objects without any decoding. In text mode (the default, or when |
| 't' is appended to the mode argument), the contents of the file are |
| returned as strings, the bytes having been first decoded using a |
| platform-dependent encoding or using the specified encoding if given. |
| |
| buffering is an optional integer used to set the buffering policy. |
| Pass 0 to switch buffering off (only allowed in binary mode), 1 to select |
| line buffering (only usable in text mode), and an integer > 1 to indicate |
| the size of a fixed-size chunk buffer. 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 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 or run 'help(codecs.Codec)' |
| for a list of the permitted encoding error strings. |
| |
| newline controls 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 '' or '\n', no translation takes place. If newline is any |
| of the other legal values, any '\n' characters written are translated |
| to the given string. |
| |
| 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. |
| |
| 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. |
