And the reason is that \ is the escape character in Python strings
so \h is seen as just h and \p as p. if you had a \t it would be seen
as a tab character etc. So to avoid that either tell Python to ignore
the escapes by using r(raw string) or use forward slashes which
work just as well in Windows as in Linux...
You'll find more on this in the side bar in my File Handling topic,
about 1/3 of the way down the page.
