The compiler should have warned you about this: backslashes indicate escape
sequences, so all your '\.' become plain old '.' when the string is parsed.
You should instead use '\\.'. The NSPredicate examples show this.
I suspect that Python has quoting semantics like Perl, so the backslashes
aren't seen as escape sequences, as they would if the string was
double-quoted.
