Python &引用；列表索引必须是整数"；-蟒蛇

我的意见如下：

"custom_fields": "[{"id":360027795053,"value":"XXXX"}, 
                   {"id":360030272393,"value":"XXX"}, 
                   {"id":360027795613,"value":XXX}, 
                   {"id":360027795393,"value":"XXX"}, 
                   {"id":360027795413,"value":"XXX"}, 
                   {"id":360030272233,"value":"XXX"},
                   {"id":360027795453,"value":["XXX"]}]"

我访问上述内容如下：

dict_conversion=json.loads(custom_fields)

properties['field_1']=dict_conversion['360027795053']['value']

 properties['field_1']=dict_conversion[1]['value']

上面给出了以下错误：

列表索引必须是整数

看起来我正在尝试按元素名称调用元素，但它不允许调用。我只能按以下索引号码拨打电话：

dict_conversion=json.loads(custom_fields)

properties['field_1']=dict_conversion['360027795053']['value']

 properties['field_1']=dict_conversion[1]['value']

但我更喜欢叫主名

任何帮助-谢谢

您可以首先转换为dict，id为键，值为其值

custom_fields = [{"id":360027795053,"value":"XXXX"},
                   {"id":360030272393,"value":"XXX"},
                   {"id":360027795613,"value":"XXX"},
                   {"id":360027795393,"value":"XXX"},
                   {"id":360027795413,"value":"XXX"},
                   {"id":360030272233,"value":"XXX"},
                   {"id":360027795453,"value":"XXX"}]
id_dict = {i['id']: i['value'] for i in custom_fields}
print(id_dict)
>>> {360027795053: 'XXXX', 360030272393: 'XXX', 360027795613: 'XXX', 360027795393: 'XXX', 360027795413: 'XXX', 360030272233: 'XXX', 360027795453: 'XXX'}

现在，如果要获取给定id的值，可以使用以下方法调用它：

print(id_dict[360027795053])
>>> XXXX

如果您不想这样做，也可以循环查看您的列表，如下所示：

search_id = 360027795053
for i in custom_fields:
    if i['id'] == search_id:
        print(i['value'])
        break

以及您的实际错误

360027795053

和

'360027795053'

是不同的事情。
