ddstable 0.0.1

Introduction

A DDS (double-dummy solver) function is available through Bo Haglund's DDS 2.9.0. For Windows, the DDS DLL is distributed with are distributed together.

The solution used here is copied from below two opensource project, credit to them

this project focus on DDS table only like below

$ ./ddstable.py
          S     H     D     C    NT
    N     -     4     2     -     3
    S     -     4     2     -     3
    E     3     -     -     -     -
    W     3     -     -     -     -

How to use it

from ddstable import ddstable
PBN = b"E:QJT5432.T.6.QJ82 .J97543.K7532.94 87.A62.QJT4.AT75 AK96.KQ8.A98.K63"
all = ddstable.get_ddstable(PBN)
print("{:>5} {:>5} {:>5} {:>5} {:>5} {:>5}".format("", "S", "H", "D", "C", "NT"))
for each in all.keys():
    print("{:>5}".format(each),end='')
    for suit in dcardSuit:
        trick=all[each][suit]
        if trick>7:
            print(" {:5}".format(trick - 6),end='')
        else:
            print(" {:>5}".format("-"),end='')
    print("")

or

>>> from ddstable import ddstable
>>> PBN = b"E:QJT5432.T.6.QJ82 .J97543.K7532.94 87.A62.QJT4.AT75 AK96.KQ8.A98.K63"
>>> ddstable.get_ddstable(PBN)
{'N': {'S': 4, 'H': 10, 'D': 8, 'C': 6, 'NT': 9}, 'S': {'S': 4, 'H': 10, 'D': 8, 'C': 6, 'NT': 9}, 'E': {'S': 9, 'H': 2, 'D': 3, 'C': 7, 'NT': 3}, 'W': {'S': 9, 'H': 2, 'D': 3, 'C': 7, 'NT': 3}}
