re.Scanner - match python dot notation

[Christian K.]

Hi,

I am trying to find a regexp to be used with re.Scanner that matches the 
'package.module.member' syntax. More specifically I want to parse 
function strings like

numpy.sin(x*a+w)

and sort out variables/constants.

This one here works using re.match but fails when used with Scanner (due 
to the grouping () I guess).

r'((?=.*[a-zA-Z])(?=.+[\.]).+)[\(\+\-]+'

I highly appreciate your comments.

Regards, christian
