I need to be able to order the values in a descending order. this is the output i have and it is in a list form, 

```
Eutherian - Bat - Microbat : 28
Avian - Other : 203
Marsupial - Macropod : 14
Eutherian - Bat - Flying Fox : 25
Reptile - Lizard : 28
Avian - Waterbird : 19
Marsupial - Koala : 13
Marsupial - Possum/Glider : 50
Reptile - Snake - Terrestrial : 18
Amphibian - Native Frog : 2
Reptile - Turtle - Freshwater : 3
Marsupial - Dasyurid : 4
Marsupial - Bandicoot : 4
Avian - Seabird/Pelican : 5
Avian - Raptor : 3
Reptile - Snake - Marine : 1
Reptile - Turtle - Marine : 2

```

i have tried using the split function but i cant get it to work and i have tried using tuples? i am a complete beginner

the result i am trying to achieve is to have the most reports to the worst to then make a pie chart showing this
