How to make this doctest work?

[Xie&Tian]

Hello

I ran across this accidentally and wonders how to make the doctest in
following code snippet work:


import doctest

def a():
     """
    >>> a = '\\r\\n'
    >>> print a


    No matter how many blank lines I add here, it just can't get enough -_-
    """
    pass

doctest.testmod()



ps: I want variable "a" to be '\r\n', but python kept telling me
        ValueError: line 4 of the docstring has inconsistent leading
whitespace: "'"
    Why can't doctest module deal with statement "a='\r\n'"?
