我有一个包含多米诺骨牌的列表(那些也是两个整数的列表),我需要找到一个多米诺骨牌的索引
例:
list_of_hand = [[[2, 5], [5, 5], [6, 5], [6, 4]], [[3, 2], [4, 5], [4, 4], [6, 1]]]
该列表是两个列表,其中包括玩家手中所有的多米诺骨牌。
如何找到多米诺
[6, 5]
的索引? 最佳答案
您可以使用一个简单的函数来搜索子列表:
x = [[[2, 5], [5, 5], [6, 5], [6, 4]], [[3, 2], [4, 5], [4, 4], [6, 1]]]
def hand_search(L, domino):
for s in L:
if domino in s:
return (L.index(s), s.index(domino))
return -1
print(hand_search(x, [6,5]))
print(hand_search(x, [6,1]))
输出:
(0, 2) # 0 is the player, 2 is the position in their hand
(1, 3) # 1 is the player, 3 is the position in their hand
只要嵌套相同,就可以根据需要扩展到任意数量的玩家。
