LF short name for the character
12 value of character in octal
10 value of character in decimal
a value of character in hex
^J keystroke on keyboard (ctrl+j)
Line Feed long name for character.
The python builtin functions ord and chr are the most useful for dealing
with character values. chr takes an integer value and returns the
corresponding string character. ord takes a string character and
returns its integer value.
ord('\n') == 10
chr(10) == '\n'
The column of decimal values is generally the most useful when working
with ord and chr.

assume fp is your file type object
fp.write('\n') # should write a linefeed
fp.write(chr(10)) # should also write a linefeed
You may need to use
to force your output out of the buffer.
