The cause of the error is easy enough.

(0.0,) * (0.0,) is undefined.  It's unclear however what you
 actually intended because the problem is incompletely specified.
 

Start with python version.  I'll assume 3.3.

Next show us what result you actually expect. Can we assume all
 tuples will have a single element in them? Are you looking to
 flatten both list and tuples,  and get a single float
 sum?

Wild guess:

x2 = [x[0]* x[0] for x in seriesxlist1];
res = sum (x2)
