Merge sort array of tuples by datetime?

I have a list looking like this:

List = [
    (0, "26-02-2019", 4),
    (1, "04-03-2019", 12),
    (2, "20-01-2019", 3),
    (3, "11-04-2019", 9),
]

I need to order them in terms of the date, in index position 1.

If it helps, to convert into the normal datetime format I can use datetime.datetime.strptime(i[1], '%d-%m-%Y') when I use a for loop.

Q: Is it possible to do a merge sort on this type of data? If so, how?

EDIT: Stop marking as duplicate - my question is to MERGE SORT not using .sort(key=lambda x: datetime.datetime.strptime(x[1], '%d-%m-%Y'))

See the `key` argument to the `sorted` function. – chepner Feb 26 '19 at 20:15

You could do`sorted(lst, key=lambda x: datetime.datetime.strptime(x[1], '%d-%m-%Y'))` – Dani Mesejo Feb 26 '19 at 20:15
What exactly are you stuck on? How to sort a list of tuples by a particular member of each? – glibdud Feb 26 '19 at 20:15
