The Alpha 2 of Python 2.4 has already been released on August 5th, and it is a little time to see today. After you have made it, share it with you.
First, I can't pay attention to it, 2.4 is built into the language in the language, before being placed in the standard library. The current use is also very flexible:
(Part of the example in the text is taken from the Python.org website)
>>> a = set ('Abracadabra') # Generate a set by a string
>>> 'Z' In a # Quick detection members exist
False
>>> A
Set (['a', 'r', 'b', 'c', 'd'])
>>> '' .join (a) # Transform the elements in the set back to the string
'arbcd'
>>> b = set ('alacazam') # another set
>>> a - b # gets a set of elements belonging to A rather than B
Set (['R', 'D', 'B'])
>>> a | b # a and b
Set (['A', 'C', 'R', 'D', 'B', 'M,' Z ',' L '])
>>> A & B # a and b
set (['a', 'c'])
>>> a ^ b # belongs to a or b but does not belong to elements they intend
Set (['R', 'D', 'B', 'M', 'Z', 'L'])
>>> a.add ('z')
>>> a.Update ('wxy')
>>> A
Set (['a', 'c', 'b', 'd', 'r', 'w', 'y', 'x', 'Z'])
>>> A.Remove ('x') # Delete a set of elements
>>> A
Set (['a', 'c', 'b', 'd', 'r', 'w', 'y', 'Z'])
Other features are trying.
