Did you look at what I, j, and k are?  They are names of objects.
When I ran your code my inequalities were different.
What you are seeing is likely some comparison of the location of the
objects over which you have no control
>>> i = a()
>>> j = a()
>>> k = a()
>>> i < j
False
>>> j < k
True
>>> i
<__main__.a instance at 0xb76d0a2c>
>>> j
<__main__.a instance at 0xb76d096c>
>>> k
<__main__.a instance at 0xb76d09ec>
>>>
