I'm pretty sure I told you to *loop* over a copy, not *remove* things 
from a copy.

what's that last line supposed to to?

here's your *original* code, changed to loop over a copy:

for x in List[:]:
      temp=[]
      print x
      for y in List:
              if x[0]==y[0]:
                      print y[0],y[1]
                      temp.append(y)
      for z in temp:
             List.remove(z)
             print 'rem', z

when run on your original data set, this prints your expected output.
