I imported functools. Now I get the below error please.


Traceback (most recent call last):
  File "test.py", line 16, in <module>
    total = sum(float(col.value) for r in iter(next_r, None) for col in r.itervalues()) 
  File "test.py", line 16, in <genexpr>
    total = sum(float(col.value) for r in iter(next_r, None) for col in r.itervalues()) 
AttributeError: 'list' object has no attribute 'itervalues'

Thanks
