collections¶
Specialised container datatypes

class
coinflip.collections.
Bins
(intervals: Iterable[numbers.Real])[source]¶ Mapping that initialises intervals as empty bins
If a key is accessed that does not exist, the nearest interval is used.
 Parameters
intervals (
Iterable[Real]
) – Nonexistent keys will round to the closest of these intervals
Examples
>>> bins = Bins([6, 3, 0, 3, 6]) >>> bins {6: 0, 3: 0, 0: 0, 3: 0, 6: 0} >>> bins[3] += 1 # n = 3 >>> bins {6: 0, 3: 0, 0: 0, 3: 1, 6: 0} >>> bins[7] += 1 # n = 6 >>> bins[11] += 1 # n = 6 >>> bins[6.5] += 1 # n = 6 >>> bins {6: 0, 3: 0, 0: 0, 3: 1, 6: 3} >>> bins[1000000] += 1 # n = 6 >>> bins {6: 1, 3: 0, 0: 0, 3: 1, 6: 3} >>> bins[0.5] += 1 # n = 0 >>> bins {6: 1, 3: 0, 0: 1, 3: 1, 6: 3} >>> del bins[6] {6: 1, 3: 0, 0: 1, 3: 4}

class
coinflip.collections.
defaultlist
(default_factory: Optional[Callable] = None)[source]¶ A list with default values
 Parameters
default_factory (
Callable
, optional)

class
coinflip.collections.
FloorDict
(dict: Dict)[source]¶ Mapping where invalid keys floor to the smallest real key
If a key is accessed that does not exist, the nearest real key that is the lessthan of the passed key is used.
 Parameters
dict (
Dict
) – Dictionary containing the keyvalue pairs to be floored to
