I'm looking in a my python book and it says when using multi-line strings,
"You can think of a text file as a string that happens to be stored on disk. Of cource, a typical file generally contains more than a single line of text. A special character or sequence of characters is used to mark the end of each line. There are numerous conventions for end-of-line markers. Python uses a single character called newline."
"You can think of a newline as the character produced when you press the <enter> key on your keyboard. Although a newline is a single character, it is represented in Python using the special notation '/n'.
Hope that helps you out. It was under the "Multi-Line Strings" section.
