Raymond Hettinger  added the comment:

I prefer to keep the example as-is.  It is an idiomatic way to loop over sets.  
The introductory text can be modified to explain that sets eliminate 
duplicates, that sets are ordered, and that sorted() puts them back in a 
deterministic order.

Eric V. Smith  added the comment:

The code is converting to a set first, then calls sorted() on that set. So 
"apple" is removed when the set is created.

I'm not sure the example should throw in creating a set while it's talking 
about sorting.

New submission from Mirwi :

>>> basket = ['apple', 'orange', 'apple', 'pear', 'orange', 'banana']
>>> for f in sorted(set(basket)):
... print(f)
...
apple
banana
orange
pear

Shouldn't 'apple' appear two times as basket is a list that allows duplicates, 
not a set?

I'm just doing my first steps into Python and may be mislead. In that case, 
sorry for the fuzz.
