I just finished learning LISTS (chapter) in Python course and there is a challege at the end - 5. Combine Sort

I did this code:

```
#Write your function here
def combine_sort(lst1, lst2):
together = sorted(lst1 + lst2)
return together
#Uncomment the line below when your function is done
print(combine_sort([4, 10, 2, 5], [-10, 2, 5, 10]))
```

I did a shorter version, that seemed to work, but I wonder, did I do it right and is there any difference with the code provided as a solution by CodeAcademy? Which is:

```
#Write your function here
def combine_sort(lst1, lst2):
together = sorted(lst1 + lst2)
all = sorted(together)
return all
#Uncomment the line below when your function is done
print(combine_sort([4, 10, 2, 5], [-10, 2, 5, 10]))
```

Cheers.
