How to get unique letters from string

Question

I am trying to find how to get unique letters in a given string.

Do we have any inbuilt method to get it?

My code:

strname='aavccbb'
strname.most_common()

Expected output:

abcv

I would have made use of set but there is no guarantee of order.

# Long form
strname='aavccbb'
lst = list(strname)
lst.sort()
print(set(lst))

# Short form
print(sorted(set(list(strname))))
