This is a list comprehension. see: https://docs.python.org/2/tutorial/datastructures.html#list-comprehensions But I would solve your problem like this: things_I_do_not_want = ['Car', 'Banana', <add all of them here>] things_I_want = [] for item in list_of_everything_I_started_with: if item not in things_I_do_not_want: things_I_want.append(item) Laura -- https://mail.python.org/mailman/listinfo/python-list
