The sets module is in both 2.3

In 2.4 I tried 'from sets import set'
Traceback (most recent call last):
File "/home/glen/set4.py", line 1, in -toplevel-
from sets import set
ImportError: cannot import name set
It did allow 'from sets import *' but when using the set command
I got some odd output...
from sets import *
a=[12,54,67,47,98,76]
b=[47,54]
print set(a)-set(b)
>>>
set(['dog','sheep,'cow'])
set([76, 98, 67, 12])
>>>
It seems to save the output from the last use, and reproduces it later,
even after a system reboot I got the same output.
Using the inbuilt commands works fine.
