[Tutor] doctest question

[Albert-Jan Roskam]

Hi,

I am using doctest and I am struggling with newlines characters (see below). One is the newline escape (backslash)
for a long dictionary definition. The other is an embedded \n in the output. I used the +NORMALIZE_WHITESPACE
directive. I also tried using a triple-quoted raw docstring. Any ideas?

While we're at it: is this a good book? http://www.packtpub.com/python-testing-beginners-guide/book
It should be complete, not too shallow, nor so detailed that is becomes too impractical.

Thanks!
