Given a Python list, I want to remove consecutive 'duplicates'. The duplicate value however is a attribute of the list item (In this example, the
tuple's first element).
[(1, 'a'), (2, 'b'), (2, 'b'), (2, 'c'), (3, 'd'), (2, 'e')]
[(1, 'a'), (2, 'b'), (3, 'd'), (2, 'e')]
dict, because order is important.
Cannot use list comprehension
[x for x in somelist if not determine(x)], because the check depends on predecessor.
What I want is something like:
mylist = [...] for i in range(len(mylist)): if mylist[i-1].attr == mylist[i].attr: mylist.remove(i)
What is the preferred way to solve this in Python?
