When i run doctest on the module, i get that error: 
 
 
 
[sm@localhost Spyca]$ python Spyca.py 
********************************************************************** 
File "Spyca.py", line 840, in

1 items had failures:

Now, when i do all the same in the interpreter: 
 
 
 
 
[sm@localhost Spyca]$ python 
Python 2.4.1 (#2, Aug 25 2005, 18:20:57) 
[GCC 4.0.1 (4.0.1-2mdk for Mandriva Linux release 
2006.0)] on linux2 
Type "help", "copyright", "credits" or "license" for 
more information. 
>>> import Spyca as S 
>>> lat = S.Latitude() 
>>> lon = S.Longitude() 
>>> seq = (None, 'myCity', None, lat, lon, 0, '') 
>>> c = S.City(seq) 
>>> print c 
myCity 
>>> repr(c) 
"[None, 'myCity', None, [0, 0 ,0, 0.0], [0, 0 ,0, 
0.0], 0, '']" 
>>> 
 
 
 
As you can see, no error in the interpreter.
