Question

我有两个列表，我想用每个列表创建一个dict，其中键值是一个字符串，然后将这两个词组合成一个，下面是我的列表：

list_1 :  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]

list_2 :  ['BACKUP_INFO', 'sqlite_sequence', 'BACKUP_INFO_SEARCH', 'BACKUP_INFO_SEARCH_content', 'BACKUP_INFO_SEARCH_segments', 'BACKUP_INFO_SEARCH_segdir', 'BACKUP_INFO_SEARCH_docsize', 'BACKUP_INFO_SEARCH_stat', 'FILE_INFO', 'FILE_INFO_SEARCH', 'FILE_INFO_SEARCH_content', 'FILE_INFO_SEARCH_segments', 'FILE_INFO_SEARCH_segdir', 'FILE_INFO_SEARCH_docsize', 'FILE_INFO_SEARCH_stat']

List_1应添加dict键值为“id”

List_2应添加dict键值为'table'

然后，上述两个词都应合并成一个词典，形成类似的东西：

{
    "output": 
     {
        "id": 1,
        "table" : BACKUP_INFO
     }
     {
        "id": 2,
        "table" :sqlite_sequence 
     }    
}

但是，我使用

获得以下输出

table_list_out = dict(zip(list_1, list_2)) return { 'output' : {'id' : list_1, 'table_name' : list_2}}：

{
    "output": {
        "id": [
            1, 
            2, 
            3, 
            4, 
            5, 
            6, 
            7, 
            8, 
            9, 
            10, 
            11, 
            12, 
            13, 
            14, 
            15
        ], 
        "table_name": {
            "1": "BACKUP_INFO", 
            "2": "sqlite_sequence", 
            "3": "BACKUP_INFO_SEARCH", 
            "4": "BACKUP_INFO_SEARCH_content", 
            "5": "BACKUP_INFO_SEARCH_segments", 
            "6": "BACKUP_INFO_SEARCH_segdir", 
            "7": "BACKUP_INFO_SEARCH_docsize", 
            "8": "BACKUP_INFO_SEARCH_stat", 
            "9": "FILE_INFO", 
            "10": "FILE_INFO_SEARCH", 
            "11": "FILE_INFO_SEARCH_content", 
            "12": "FILE_INFO_SEARCH_segments", 
            "13": "FILE_INFO_SEARCH_segdir", 
            "14": "FILE_INFO_SEARCH_docsize", 
            "15": "FILE_INFO_SEARCH_stat"
        }
    }
}

Answer 1

您可以使用列表理解：

list_1 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
list_2 = ['BACKUP_INFO', 'sqlite_sequence', 'BACKUP_INFO_SEARCH', 'BACKUP_INFO_SEARCH_content', 'BACKUP_INFO_SEARCH_segments', 'BACKUP_INFO_SEARCH_segdir', 'BACKUP_INFO_SEARCH_docsize', 'BACKUP_INFO_SEARCH_stat', 'FILE_INFO', 'FILE_INFO_SEARCH', 'FILE_INFO_SEARCH_content', 'FILE_INFO_SEARCH_segments', 'FILE_INFO_SEARCH_segdir', 'FILE_INFO_SEARCH_docsize', 'FILE_INFO_SEARCH_stat']
new_dict = {'output':[{'id':a, 'table':b} for a, b in zip(list_1, list_2)]}

输出：

{'output': [{'table': 'BACKUP_INFO', 'id': 1}, {'table': 'sqlite_sequence', 'id': 2}, {'table': 'BACKUP_INFO_SEARCH', 'id': 3}, {'table': 'BACKUP_INFO_SEARCH_content', 'id': 4}, {'table': 'BACKUP_INFO_SEARCH_segments', 'id': 5}, {'table': 'BACKUP_INFO_SEARCH_segdir', 'id': 6}, {'table': 'BACKUP_INFO_SEARCH_docsize', 'id': 7}, {'table': 'BACKUP_INFO_SEARCH_stat', 'id': 8}, {'table': 'FILE_INFO', 'id': 9}, {'table': 'FILE_INFO_SEARCH', 'id': 10}, {'table': 'FILE_INFO_SEARCH_content', 'id': 11}, {'table': 'FILE_INFO_SEARCH_segments', 'id': 12}, {'table': 'FILE_INFO_SEARCH_segdir', 'id': 13}, {'table': 'FILE_INFO_SEARCH_docsize', 'id': 14}, {'table': 'FILE_INFO_SEARCH_stat', 'id': 15}]}

Answer 2

从外观上看，你想要的输出是不可能的。请注意，有多个值对应于键：＆＃34;输出＆＃34;。

可能是这样的，其中对应于＆＃39;输出＆＃39;是一个词典列表。

return {'output': [{'id': x, 'table': y} for x, y in zip(list1, list2)]}

Answer 3

你可以循环使用它，我确定它有一个单行，但这很清楚。

output = {"output":{} }
for i in xrange(0, len(list_1)):
    output["output"][list_2[i]] = list_1[i]

print output

将String添加到列表项，然后在python中创建一个dict
