'\n' is not a CRLF in memory, on any platform (that I know).
It generates CRLF whenever it is written to a file opened for
text output (mode 'w'). Likewise, reading a file in text mode,
CRLF ('\r\n') gets converted to '\n'. The C standard library
for Windows does this.
So yes, '\n' is treated as a platform-independent newline, and
it is not Python that handles this, but C.
Not sure about Java. Perhaps Jython has to emulate this behavior.
