I found the sequence \\newline in a list of escape sequences in the python documentation. I wonder how it is used and for what. At least in my interpreter it se
The documentation you are alluding to is explaining how a backslash followed by a literal newline is ignored, as if the next line were physically joined with the line on which the starting backslash was found.
The string \newline' has no special meaning; it is exactly what you say you think it is.
