Python 从2d字典数组中提取特定的键/值
嗨，我有一个2d字典数组，我想从中提取满足特定条件的第一个键的第一个值，并将它们放在另一个2d数组中。以下是矩阵“coord_curva_testo”（部分）： 我想为每一行提取第一个具有键8、键10或键12的字典，并且从每个键中只提取第一个值。例如，在第一排，这对夫妇是（8,10）、（10,24）和（12,30） 我是Python新手，我发现最适合我的语言，下面是我的代码（如果您觉得有点凌乱，请原谅）： 引述 但结果是每一行都有与第一行相同的词典Python 从2d字典数组中提取特定的键/值,python,arrays,dictionary,2d,Python,Arrays,Dictionary,2d,嗨，我有一个2d字典数组，我想从中提取满足特定条件的第一个键的第一个值，并将它们放在另一个2d数组中。以下是矩阵“coord_curva_testo”（部分）： 我想为每一行提取第一个具有键8、键10或键12的字典，并且从每个键中只提取第一个值。例如，在第一排，这对夫妇是（8,10）、（10,24）和（12,30） 我是Python新手，我发现最适合我的语言，下面是我的代码（如果您觉得有点凌乱，请原谅）： 引述 但结果是每一行都有与第一行相同的词典 [[{8: 10}, {10: 24}, {1

你好，CDJB，感谢您提供的解决方案。我之所以这么做是因为有些字典里没有键12。所以我想知道如何修改onliner for loop。您可以在try:except:pass语句中包装ret.append行-如果没有字典的键为12，那么它将跳过该键值。您好，CDJB，谢谢您的解决方案。我之所以这么做是因为有些字典里没有键12。所以我想知道如何修改onliner for循环。您可以在try:except:pass语句中包装ret.append行-如果没有字典的键为12，那么它将跳过该键值。
