Changing stacked labels new line character to other than comma using ArcMap

Trying to execute some stacked labels with little bit of Python from the examples given here:
https://desktop.arcgis.com/en/arcmap/10.3/map/working-with-text/about-building-label-expressions.htm

The example for Python stacked labels uses a comma to denote the new line character but some of my fields have commas in them throwing it off.

Can the character be other than a comma?

Tried just using a blank space and it didn’t accept that as an argument. I know semi colon is generally bad Python practice and tried it anyway (didn’t work, wouldn’t parse).

Suggestions?
