Test for consistency in ordered bidicts after handling duplicate keys/values
|
|
(when passing python's -O flag, this would previously fail
|
|
due to reliance on side effects in assert statements)::
|
|
|
|
>>> from bidict import OrderedBidict, DuplicationError, RAISE, OVERWRITE
|
|
>>> b = OrderedBidict([(0, 1)])
|
|
>>> try:
|
|
... b.update([(0, 2), (3, 4), (5, 4)])
|
|
... except DuplicationError:
|
|
... pass
|
|
>>> len(b.inv)
|
|
1
|
|
>>> try:
|
|
... b.putall([(2, 1), (2, 3)], on_dup_key=RAISE, on_dup_val=OVERWRITE)
|
|
... except DuplicationError:
|
|
... pass
|
|
>>> len(b)
|
|
1
|
|
>>> b.forceupdate([(0, 1), (2, 3), (0, 3)])
|
|
>>> len(b)
|
|
1
|
|
>>> 2 in b
|
|
False
