Transform “list of tuples” into a flat list or a matrix

Question

With Sqlite, a \"select..from\" command returns the results \"output\", which prints (in python):

>>print output
[(12.2817, 12.2817), (0, 0), (8.52, 8.         


        

Answer 1

Or you can flatten the list like this:

reduce(lambda x,y:x+y, map(list, output))
