我已经写了一个国际象棋程序，目前正在通过编码检查工作。如何确定清单中哪一个（词典中的键）中有kingpos？
下面的示例应给出'ksbishop'的答案。
kingpos=(5,1)
movesdict={'ksknight': [(8, 3), (5, 2), (6, 3)],
'ksbishop': [(3, 6), (4, 7), (5, 8), (1, 4), (1, 6), (3, 4), (4, 3), (5, 1), (6, 1)],
'king': [(6, 1), (5, 2), (4, 1)],
'queen': [(4, 5), (2, 4), (1, 3), (2, 6), (1, 7), (4, 4)],
'qsknight': [(3, 3), (1, 3)]}
if kingpos in [z for v in movesdict.values() for z in v]:
# find out which key has it
最佳答案
您可以使用列表理解：
>>> [key for key in movesdict if kingpos in movesdict[key]]
['ksbishop']
