Removing 'New Line' from a python script

[ajaymccollum]

I've got a python script running the input for a 16 key matrix keypad. I've got a node that runs the script and outputs the keypad's inputs. After every keystroke, it adds a line break or something that I don't know enough about programming to remove from the code itself.
I was hoping there was a way to filter that line break (or whatever it's called) out in node red and just leave the character.

I've figured out an extremely round-about way that works, but is laughably inefficient, involving a split and a switch with 16 outputs; just not pleasant to work with.
Thanks for the time.

use the string.replace() method https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace in a function node with this regex:

something like:

msg.payload = msg.payload.replace(/[\n\r]+/g,““);
return msg;

I think trim() will do it too.
msg.payload = msg.payload.trim();
return msg

never tried trim with a carriage return, would be good to know if it works.
