New submission from Oskar Weser:

There is a code example about the set type found under:

It reads as:
>>> basket = {'apple', 'orange', 'apple', 'pear', 'orange', 'banana'}
>>> print(basket)                      # show that duplicates have been removed
{'orange', 'banana', 'pear', 'apple'}
>>> 'orange' in basket                 # fast membership testing
>>> 'crabgrass' in basket

>>> # Demonstrate set operations on unique letters from two words
>>> a = set('abracadabra')
>>> b = set('alacazam')
>>> a                                  # unique letters in a
{'a', 'r', 'b', 'c', 'd'}
>>> a - b                              # letters in a but not in b
{'r', 'd', 'b'}
>>> a | b                              # letters in either a or b

I read "either a or b" as "a .EXOR. b". Shouldn't it be:
>>> a | b                              # letters in a or b
I don't speak English as a native language, so perhaps I am wrong.
