我正在寻找在嵌套字典中返回值的最有效方法。
在代码的这一点上，航空公司的名称（例如＆＃39; Delta＆＃39;）和票价等级（例如＆＃39; N＆＃39;）已经由用户输入并使用re进行验证。变量＆＃39; airline_name＆＃39;和＆＃39; fare_class＆＃39;已定义。有多个票价类包含相同的值; ＆＃39;台达＆＃39; ＆GT; ＆＃39; F＆＃39; ＆＃39; J＆＃39; ＆GT; ＆＃39; 2＆＃39;
使用传入的变量名称＆＃39; airline_name＆＃39;搜索嵌套字典值（例如＆＃39; 1.5＆＃39;）的最佳方法是什么？和＆＃39; fare_class＆＃39;？感谢您的反馈！ （如果我需要重组我的词典，我也非常乐意）
`FARE_CLASS_MULTIPLIER_DICTIONARY = {

}
答案 0 :(得分：0)
我会对其进行重组，因此每个fare_class都是给定航空公司字典中的关键字。因此，达美的字典将成为
