filtering elements from list of lists in Python?

Question

I want to filter elements from a list of lists, and iterate over the elements of each element using a lambda. For example, given the list:

a = [[1,2,3],[4,5         


        

Answer 1

You can do something like

>>> a=[[1,2,3],[4,5,6]]
>>> filter(lambda (x,y,z),: x+y+z>6, a)
[[4, 5, 6]]

Using the deconstruction syntax.
