I want to write a piece of code to a file in this format

digraph fsm {
rankdir="LR" 

f.write("digraph fsm "+\n+" {rankdir="LR"")

this gives me an error ? can someone tell me the exact formatting for this line ?

The problem is that you are trying to treat the \n as a variable, it isn't it is a character. So change this:

f.write("digraph fsm "+\n+" {rankdir="LR"")

To this:

f.write("digraph fsm \n {rankdir=\"LR\"")

and you should have better results.

NOTE - Untested code.

Basically, what that does is puts the new line character in the string instead of trying to add it in (using concatenation). It also escapes the double quotes which you are wanting in the output file. This tells python not to try ending the string at the double quote like it would normally (\").

Hope that helps.
