endplay.dds.analyse

Analysis functions from the DDS library, which calculate the double dummy number of tricks available given a play history.

Classes:

`SolvedPlay`(data)
`SolvedPlayList`(data)

Functions:

`analyse_all_plays`(deals, plays[, ...])	Optimized version of analyse_play for multiple deals which uses threading to speed up the calculation
`analyse_all_starts`(deals[, declarer_is_first])	Optimized version of analyse for multiple deals which uses threading to speed up the calculation
`analyse_play`(deal, play[, declarer_is_first])	Calculate a list of double dummy values after each card in play is played to the hand.
`analyse_start`(deal[, declarer_is_first])	Calculate the most tricks declarer can make.

endplay.dds.analyse.analyse_all_plays(deals: Iterable[Deal], plays: Iterable[Iterable[Card]], declarer_is_first: bool = False) → SolvedPlayList: Optimized version of analyse_play for multiple deals which uses threading to speed up the calculation

endplay.dds.analyse.analyse_all_starts(deals: Iterable[Deal], declarer_is_first: bool = False) → list[int]: Optimized version of analyse for multiple deals which uses threading to speed up the calculation

endplay.dds.analyse.analyse_play(deal: Deal, play: Iterable[Union[Card, str]], declarer_is_first: bool = False) → SolvedPlay: Calculate a list of double dummy values after each card in play is played to the hand. This returns len(play)+1 results, as there is also a result before any card has been played

endplay.dds.analyse.analyse_start(deal: Deal, declarer_is_first: bool = False) → int

Calculate the most tricks declarer can make.

Parameters:

deal – The deal to analyse
declarer_is_first – The algorithm assumes that the person who leads is to the left of the declarer (as would be the case with the first card led to a hand), but to return the result as seen from the leader’s perspective you can set this to True
