hi,

I've already read many pages on this but I'm not able to separate the
string 'R0\1.2646\1.2649\D' in four elements, using the \ as the separator.

a='R0\1.2644\1.2344\D'
re.sub(r'\'','ff',a)  does nothing
and why must I write two '' after the \?  If I hadn't used r I would
understand...

how should I do it?

Luis
