我有一个RDD，其数据如下所示：
[‘ID: <166.1079>\nDate: 7 Dec 2010 16:06:42\nOwner: Mary Jones\nLab-Techs: Bob Chandra\nHarry Alley\n Julie Stevens\nNotes: West Position\nTemp: 1.0 C\nX-FileName: temp-g\nX-Storage: 3544-ABC
X-Location: Building-A’]
它是一个实验室记录，一个文本文件。我有这个python代码无法正常工作。它不是正确地拆分字段然后将每个字段放在他们尊重的RDD中。这是代码：
lab_data = sc.textFile('data_file')
fields = lab_data.map(lambda x: x.split('Notes:')(0).split('\n')
ID_field = fields(0).map(lambda x: x.split(':')(1).trim())
date_field = fields(1).map(lambda x: x.split(':')(1).trim())
owner_field = fields(2).map(lambda x: x.split(':')(1).trim())
基本上，我试图抓住ID，日期和所有者等前三个字段，但忽略了所有其他字段。因此，字段RDD将具有如下值：
ID field = <166.1079>
Date field = 7 Dec 2010 16:06:42
Owner field = Marry Jones
你能帮我纠正一下代码吗？

要解析列表中的实验室记录的字符串，您可以执行以下操作：
