Question

我尝试使用python将有关API流量的信息保存到CSV文件。

我希望数据位于csv输出中的标记名称下面。这是每10分钟循环一次，因为我想获得特定道路伸展有多糟糕的图表/历史数据。

基本上看起来像这样，

Traffic Delay - Length In Meters - Departure Time - etc
Data at 0time - Data at 0time - Data at 0time - etc
Data at10time - Data at10time - Data at10time - etc

在此示例中，标题是交通行程时间，以米为单位的长度，出发时间和以秒为单位的交通延误。我目前正在使用的脚本如下。我已经开始为标题制作一个单独的字典，但我正在奋斗的城镇正确地整理它。任何蟒蛇大师能指导这个noobie吗？

from lxml import etree
import urllib.request
import csv
import time

#append to list next
def handleSummary(summary):

   tagsOfInterest=["noTrafficTravelTimeInSeconds", "lengthInMeters", "departureTime", "trafficDelayInSeconds"]  # whatever

   #list to use for data analysis
   global data
   global header
   header = tagsOfInterest
   data = []
   #create header dictionary that includes the data to be appended within it. IE, Header = {TrafficDelay[data(0)]...etc
   for child in summary:
       if 'summary' in child.tag:
          for elem in child:
              for item in tagsOfInterest:
                  if item in elem.tag:
                      data.append(elem.text)

#Parse the xml

def parseXML(xmlFile):
    while True:

            with urllib.request.urlopen("https://api.tomtom.com/routing/1/calculateRoute/-37.79205923474775,145.03010268799338:-37.798883995180496,145.03040309540322:-37.807106781970354,145.02895470253526:-37.80320743019992,145.01021142594075:-37.7999012967757,144.99318476311566:?routeType=shortest&key=notakey&computeTravelTimeFor=all") as fobj:
                xml = fobj.read()
            root = etree.fromstring(xml)
            for child in root:
                if 'route' in child.tag:
                    handleSummary(child)

               # Write CSV file
                    with open('datafile.csv', 'a') as fp:
                        writer = csv.writer(fp, delimiter=' ')
                # writer.writerow(["your", "header", "foo"])  # write header
                        writer.writerow(data)
                    with open('datafile.csv', 'r') as fp:
                        reader = csv.reader(fp, quotechar='"')
            # next(reader, None)  # skip the headers
                        data_read = [row for row in reader]
                    print(data_read)
            time.sleep(600)


if __name__ == "__main__":
   parseXML("xmlFile")

谢谢Stack！
