itemlist isn't a string, it's presumably a list.   If you pass a list to 
string, it'll turn it into a string, using approximately the following 
rules:

Put brackets on the end, and between them call repr() on each item of 
the list, separating the items with commas.

If all you like the rest of it, but don't want the brackets, try (untested)

    print('And here it is in alphabetical order:', 
str(itemList).strip('[]'))

This explicitly converts the list to a string, then strips both ends of 
the specified characters.
