This does not what I want it to do:
>>> a = [[]] * 6
>>> a[3].append('X')
>>> a
[['X'], ['X'], ['X'], ['X'], ['X'], ['X']]
This does what I want:
>>> b = [[] for _ in range(6)]
>>> b[3].append('X')
>>> b
[[], [], [], ['X'], [], []]
The first is clear and wrong. The second is hairy and right.
Is there a way to do it clear and right?
