Getting element from a list

Hi All,

I have a list:

[((5,4), 'South' , 1), ((4,5), 'West', 1)]

And I'm trying to get the co-ordinates out of it, but I have no idea how, any advice would be greatly appreciated.

My list is called successors and I've tried:

successors[0] 

but of course that just gets the whole of the first element. The list is defined as (co-ordinate, action, time)

Thanks
