You can do:
old_list = [
['ID 1d6b:0002'],
['ID 1d6b:0002'],
['ID 1d6b:0001'],
['ID 1d6b:0001'],
['ID 1d6b:0001'],
['ID 1d6b:0001'],
['ID 1d6b:0001'],
['ID 0b38:0010'],
['ID 093a:2510']]
new_list = [x[0] for x in old_list]
This uses list comprehension to create a new list that contains the first elements ([0]) all on the lists in the old list.
Hope that helps.

Please provide some details to your answer like what new_list = [x[0] for x in old_list] is doing. I assume the OP can't understand this as per the level of his/her question. :) – ρss Apr 02 '14 at 07:32
