lo there all.

i have a list of lists that i want to build, only if an item is not in the
list already.

kinda like this
new_list = []
for item in lists: # item will look something like [var1, var2, var3]
    if item[0] in new_list ( only the first element of each list ) like
new_list[0][0]

basicly, i want to know if item[0]   is one of the items[0] in my new_list

whats a good pythonic way to do this? i mean, i have a couple of way to do
this, but they are ugly.

shawn
