DiceTable and DetailedDiceTable

The two DiceTable classes are below. They inherit from dicetables.additiveevents.AdditiveEvents

class dicetables.dicetable.DiceTable(events_dict, dice_record)[source]
classmethod new()
dice_data()[source]
get_list()[source]
Returns:sorted copy of dice list: [(die, number of dice), …]
number_of_dice(query_die)[source]
weights_info()[source]
Returns:str: complete info for all dice
add_die(die, times=1)[source]
Parameters:
  • die – any subclass of ProtoDie: Die, ModDie, WeightedDie, ModWeightedDie, Modifier, StrongDie, Exploding, ExplodingOn
  • times – int>= 0
remove_die(die, times=1)[source]
Parameters:
  • die – any subclass of ProtoDie: Die, ModDie, WeightedDie, ModWeightedDie, Modifier, StrongDie, Exploding, ExplodingOn
  • times – 0 <= int <= number of “die” in table

Here is a quick demo of number_of_dice and weights_info

>>> import dicetables as dt
>>> table = dt.DiceTable.new().add_die(dt.Die(6), 2).add_die(dt.WeightedDie({1: 2, 3: 1}))
>>> print(table.weights_info())
1D3  W:3
    a roll of 1 has a weight of 2
    a roll of 2 has a weight of 0
    a roll of 3 has a weight of 1
<BLANKLINE>
2D6
    No weights
>>> table.number_of_dice(dt.WeightedDie({1: 2, 2: 0, 3: 1}))
1
>>> table.number_of_dice(dt.Die(6))
2
>>> table.number_of_dice(dt.Die(100))
0
class dicetables.dicetable.DetailedDiceTable(events_dict, dice_record, calc_includes_zeroes=True)[source]

DetailedDiceTable is a dicetable that owns a dicetables.eventsinfo.EventsCalculations. This is accessed from the .calc property and you can set whether it includes zero values with calc_includes_zeros. Owning an EventsCalculations means that it uses more memory.

info
calc
calc_includes_zeroes
switch_boolean()[source]
Returns:a new DetailedDiceTable with the calc_includes_zeroes boolean switched

You can instantiate any DiceTable or DetailedDiceTable with any data you like. This allows you to create a DiceTable from stored information or to copy. dice_data returns the correct input to instantiate a new DiceTable, which is a dicetables.dicerecord.DiceRecord (See below for details). To get consistent and sorted output for dice, use get_list. Equality testing is by: - type - get_dict()- - dice_data() - (and calc_includes_zeroes for DetailedDiceTable).

>>> ten_d_six = dt.DiceTable.new()
>>> ten_d_six = ten_d_six.add_die(dt.Die(6), 10)
>>> events_record = ten_d_six.get_dict()
>>> dice_record = ten_d_six.dice_data()
>>> new_ten_d_six = dt.DiceTable(events_record, dice_record)
>>> print(new_ten_d_six)
10D6
>>> record = dt.DiceRecord({dt.Die(6): 10})
>>> also_ten_d_six = dt.DetailedDiceTable(new_ten_d_six.get_dict(), record, calc_includes_zeroes=False)
>>> ten_d_six.get_dict() == new_ten_d_six.get_dict() == also_ten_d_six.get_dict()
True
>>> ten_d_six.get_list() == new_ten_d_six.get_list() == also_ten_d_six.get_list()
True
>>> ten_d_six == new_ten_d_six
True
>>> ten_d_six == also_ten_d_six  # False by type
False
>>> isinstance(also_ten_d_six, dt.DiceTable)
True
>>> type(also_ten_d_six) is dt.DiceTable
False

You can also remove dice, but this will raise an error if you remove too many.

>>> table = dt.DiceTable.new().add_die(dt.Die(4), 10)
>>> table.remove_die(dt.Die(4), 7)
<DiceTable containing [3D4]>
>>> table.get_list()
[(Die(4), 10)]
>>> table.remove_die(dt.Die(4), 11)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
DiceRecordError: Tried to create a DiceRecord with a negative value at Die(4): -1

DetailedDiceTable.calc_includes_zeroes defaults to True. The only way to change this property is with the switch_boolean method, which returns a new DetailedDiceTable that is identical to the original, except with calc_includes_zeroes switched.

>>> d_table = dt.DetailedDiceTable.new()
>>> d_table.calc_includes_zeroes
True
>>> d_table = d_table.add_die(dt.StrongDie(dt.Die(2), 2))
>>> print(d_table.calc.full_table_string())
2: 1
3: 0
4: 1
<BLANKLINE>
>>> d_table = d_table.switch_boolean()
>>> the_same = dt.DetailedDiceTable({2: 1, 4: 1}, d_table.dice_data(), False)
>>> d_table == the_same
True
>>> print(d_table.calc.full_table_string())
2: 1
4: 1
<BLANKLINE>
>>> d_table = d_table.add_die(dt.StrongDie(dt.Die(2), 2))
>>> print(d_table.calc.full_table_string())
4: 1
6: 2
8: 1
<BLANKLINE>
>>> d_table = d_table.switch_boolean()
>>> d_table == the_same
False
>>> print(d_table.calc.full_table_string())
4: 1
5: 0
6: 2
7: 0
8: 1
<BLANKLINE>

The DiceRecord

class dicetables.dicerecord.DiceRecord(dice_number_dict)[source]

This is an immutable record of dice. add_die, remove_die and new return new DiceRecord without altering the original. You can instantiate one with {dice_object: number_of_dice}. Trying to create a DiceRecord with a negative number of dice will raise an error.
