[Tutor] Question about the raw string

[JiangShan]

Hi everyone, 


       I am studying the python 3 and I am confused about the raw string. Why does the python interpreter do not escape the single backslash  before the quotes even I add a "r" before the string.  The following is an example:
       >>> print(r"\")
      
        SyntaxError: EOL while scanning string literal
       >>> print(r"\\")
        \\
        >>>
