I have array example is following:

```
array_store = ['01-42.0-19.5-100-26.25-46.94-D', '01-61.0-19.5-100-26.25-51.69-C', '36.0-1.0-100-25.0-40.5-D', '52.0-19.5-70-35.0-44.12-A']

```

I want to sort the array\_store in ascending alphabetical order with: A, B, C, D, E, F,.... With the last character of the element in the array.

**Except:** I want to

```
array_store = ['52.0-19.5-70-35.0-44.12-A', '01-61.0-19.5-100-26.25-51.69-C', '01-42.0-19.5-100-26.25-46.94-D', '36.0-1.0-100-25.0-40.5-D']

```

I'm trying code, but don't success:

```
mylist = list(dict.fromkeys(array_store))
mylist.sort()

```

Please help me and thank you so much!
