See below.
Parameters:
- text - str/unicode - The text to be written.
- encoding - str - The Unicode encoding that will be used.
This is ignored if 'text' isn't a Unicode string.
- errors - str - How to handle Unicode encoding errors.
Default is 'strict'. See help(unicode.encode) for the
options. This is ignored if 'text' isn't a Unicode
string.
- linesep - keyword argument - str/unicode - The sequence of
characters to be used to mark end-of-line. The default is
os.linesep. You can also specify None; this means to
leave all newlines as they are in 'text'.
- append - keyword argument - bool - Specifies what to do if
the file already exists (True: append to the end of it;
False: overwrite it.) The default is False.
--- Newline handling.
write_text() converts all standard end-of-line sequences
('\n', '\r', and '\r\n') to your platform's default end-of-line
sequence (see os.linesep; on Windows, for example, the
end-of-line marker is '\r\n').
If you don't like your platform's default, you can override it
using the 'linesep=' keyword argument. If you specifically want
write_text() to preserve the newlines as-is, use 'linesep=None'.
This applies to Unicode text the same as to 8-bit text, except
there are three additional standard Unicode end-of-line sequences:
u'\x85', u'\r\x85', and u'\u2028'.
(This is slightly different from when you open a file for
writing with fopen(filename, "w") in C or open(filename, 'w')
in Python.)
--- Unicode
If 'text' isn't Unicode, then apart from newline handling, the
bytes are written verbatim to the file. The 'encoding' and
'errors' arguments are not used and must be omitted.
If 'text' is Unicode, it is first converted to bytes using the
specified 'encoding' (or the default encoding if 'encoding'
isn't specified). The 'errors' argument applies only to this
conversion.
