Funky. However, very logical. You can also write:

(1,2,3,4,)

instead of

(1,2,3,4)

The syntax is very clear and logical. (As usual when working with 
python.) Try to add one comma for each element - that will do the stuff.
Most of the languages are not so straightforward - they forbid the last 
comma.
Python is the best. :-)
