Question

我在拆分列表中的字符串时遇到问题。该代码应该拆分列表中的字符串，然后将其输入到消息中以通过电子邮件发送。

def report(db_connection, hours_back):
    #create a string out of all the measurements
    time_now = datetime.datetime.now()
    time_before = time_now - datetime.timedelta(hours=hours_back)
    measurements = select_measurements_for_report(db_connection, hours_back)

    split = measurements.split(',')
    new_measurements = [split.split() for i in sents if i]

    message = """\
    Report data from {0} to {1}

    {2}

    """.format(time_before, time_now, new_measurements)

    send_mail(message)

这是输入到测量中的示例测量

[Measurement(measurementID=1, startTime=1555960632.4752572, endTime=1555960832.4752572, duration=100.0, channel=1, dataCounters=None), Measurement(measurementID=2, startTime=1555960532.4752572, endTime=1555960732.4752572, duration=100.0, channel=1, dataCounters=None), Measurement(measurementID=3, startTime=1555960432.4752572, endTime=1555960632.4752572, duration=100.0, channel=1, dataCounters=None), Measurement(measurementID=4, startTime=1555960332.4752572, endTime=1555960532.4752572, duration=100.0, channel=1, dataCounters=None)]

我期望输出如下：

[measurementID=1, startTime=1555960632.4752572, endTime=1555960832.4752572, duration=100.0, channel=1, dataCounters=None), measurementID=2, startTime=1555960532.4752572, endTime=1555960732.4752572, duration=100.0, channel=1, dataCounters=None), measurementID=3, startTime=1555960432.4752572, endTime=1555960632.4752572, duration=100.0, channel=1, dataCounters=None), measurementID=4, startTime=1555960332.4752572, endTime=1555960532.4752572, duration=100.0, channel=1, dataCounters=None)]

/ AttributeError：“列表”对象没有属性“拆分”
