唯一列出字典中的值

Question

我试图在字典值中有唯一的列表。我已经实现了将这个唯一性用于列表列表我的疑问是如何将数据写回字典。到目前为止，这是我所做的：  final_dict = {'SELECT: AutoSelect DF2F': [['D80', 'FoldersDF2FAutoSelect'], ['DF90', 'FoldersDF2FAutoSelect'], ['DF80', 'FoldersDF2FAutoSelect'], ['DF90', 'PB:FoldersDF2FAutoSelect']], 'SELECT: TB70001': [['DF80', 'FolderSelected'], ['DF90', 'PB:FolderSelected'], ['DF80', 'FolderSelected'], ['DF90', 'FolderSelected']]}    for v in final_dict.values():        unique_data = [list(x) for x in set(tuple(x) for x in v)]如果你看我的字典有这么多重复的列表一个值。我已经消除了重复项。现在，我将如何将其转换回 dict？

Answer 1

使用简单的迭代

前任：

final_dict = {'SELECT: AutoSelect DF2F': [['D80', 'FoldersDF2FAutoSelect'], ['DF90', 'FoldersDF2FAutoSelect'], ['DF80', 'FoldersDF2FAutoSelect'], ['DF90', 'PB:FoldersDF2FAutoSelect']], 'SELECT: TB70001': [['DF80', 'FolderSelected'], ['DF90', 'PB:FolderSelected'], ['DF80', 'FolderSelected'], ['DF90', 'FolderSelected']]}

for k, v in final_dict.items():

    final_dict[k] = [list(x) for x in set(tuple(x) for x in v)]

pprint(final_dict)

输出：

{'SELECT: AutoSelect DF2F': [['DF90', 'FoldersDF2FAutoSelect'],

                             ['D80', 'FoldersDF2FAutoSelect'],

                             ['DF90', 'PB:FoldersDF2FAutoSelect'],

                             ['DF80', 'FoldersDF2FAutoSelect']],

 'SELECT: TB70001': [['DF90', 'PB:FolderSelected'],

                     ['DF80', 'FolderSelected'],

                     ['DF90', 'FolderSelected']]}

Answer 2

你快到了，在 for 循环中，跟踪键k，并保存unique_data在该键的字典中：

final_dict = {'SELECT: AutoSelect DF2F': [['D80', 'FoldersDF2FAutoSelect'], ['DF90', 'FoldersDF2FAutoSelect'], ['DF80', 'FoldersDF2FAutoSelect'], ['DF90', 'PB:FoldersDF2FAutoSelect']], 'SELECT: TB70001': [['DF80', 'FolderSelected'], ['DF90', 'PB:FolderSelected'], ['DF80', 'FolderSelected'], ['DF90', 'FolderSelected']]}

for k,v in final_dict:

    unique_data = [list(x) for x in set(tuple(x) for x in v)]

    final_dict[k] = unique_data
