comparing two lists

[Davor Levicki]

i have two lists

list1 = ['01:15', 'abc', '01:15', 'def', '01:45', 'ghi' ]
list2 =  ['01:15', 'abc', '01:15', 'uvz', '01:45', 'ghi' ]

and when I loop through the list 


list_difference = []
for item in list1:

  if item not in list2:
    list_difference.append(item)


and I managed to get the difference, but I need time as well
because it is a separate item and 'uvz' does not mean to me anything in the list with a few thousand entries.
I tried to convert it to the dictionary, but it overwrites with last key:value {'01:15' : 'def'}
