In the Python manual, I found the sequence \newline in a list of escape sequences. This article from Scaler demonstrated to me that it does not represent itself but is transformed into another character or set of characters that, like newline, may be difficult or impossible to describe directly.
I'm curious how and why it's used. This appears to be translated as 'n' + 'ewline' in my interpreter:
>>> print('\newline')
ewline
