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
It does almost what it says it does. The \n is the escape sequence for printing a new line in a text string. The rest of the string is what is to be printed
print ("\newline')
ewline
Lets not forget the venerable \r for carriage return. There are a few more shown here,

A backslash means the next character is special.
\n means newline
\t means tab
\\ means \ so for example, "C:\\Program Files" will be interpreted to mean "C:\Program Files".
