While we are simplifying... (Having imported add from operator):

[reduce(add,l) for l in lost_of_lists]

I must say - for single iterators, where there seems to be little
controversy over syntax - this list comprehension stuff can be really
neat :)

Although - for those who haven't installed it (like me), this works
nicely:

map(lambda l: reduce(add,l), list_of_lists)
