Dear all,
I've written a class State that subclasses tuple. The class has a method
move_state that takes a move and returns a new state object representing
the new state of the game.
I would expect S1 and S3 to be equal on the last line here, but they are
not.
>>> import game
>>> S = game.State()
>>> S1 = S.move_state(1).move_state("SWAP")
>>> S2 = S.move_state(1)
>>> S3 = S2.move_state("SWAP")
>>> S1 == S3
False
Printing the two states shows that they have very different internal states.
>>> print S1
(8, 8, 8, 8, 8, 8, 0)
1 0
(7, 7, 7, 7, 7, 7, 7)
>>> print S3
(7, 7, 7, 7, 7, 7, 7)
0 1
(0, 8, 8, 8, 8, 8, 8)
If anyone is interested, State represents the state of a 7 7 Kalah board.
The full code is on pastebin http://pastebin.com/tUh0W5Se
Are my expectations faulty? (I hope not)
Have I made some mistake in my code to get these results?
Thanks in advance,
Colin Caine
