Question

我不确定，可能答案已经在这里了，但是由于我的＆＃34; noob-status＆＃34;我很难理解所有问题是否真的与我的问题有关并且相信我，我从昨天早上起就试图寻找解决方案，明天我必须完成，所以我走了：

我需要用Python27编写一个脚本，它自动将带有坐标的给定CSV文件转换为可用于谷歌地球的KML文件。

这是我到目前为止所得到的：

# imports the module urllib2 to open URLs
import urllib2
# ask for URL and load it
# Bsp.: http://koenigstuhl.geog.uni-heidelberg.de/~bhoefle/geoscripting/GPS_track_HD_Bodensee.csv
URL = raw_input("Enter the URL to your CSV-file: ")
response = urllib2.urlopen(URL)
html = response.read()
#print html

Zielverzeichnis = raw_input("Enter the path where you would like to store the file:")
Dateiname = "/" + raw_input("Name your file:") + ".kml"
#print Dateiname
#print Zielverzeichnis
#print Zielverzeichnis + Dateiname
Tabelle = Zielverzeichnis + Dateiname
fileobj = file(Tabelle, "w")
with open(Tabelle, "w") as writefile:
    writefile.write(html)


#import csv
#data = csv.reader(open(Tabelle), delimiter = ',')
f = open(Tabelle, 'w')
f.write("<?xml version='1.0' encoding='UTF-8'?>\n")
f.write("<kml xmlns='http://www.opengis.net/kml/2.2'>\n")
f.write("<Placemark>\n")
f.write("<name>" + Dateiname +"</name>\n")
f.write("<MultiGeometry>\n")
f.write("<LineString>\n")
f.write("<coordinates>\n")

html2 = html.split()
Koordinaten = html2[3:1003]


#Koordinaten.insert([n*30], ]])
f.writelines(Koordinaten)

f.close()
#with open(Tabelle) as rfile:
#    lines = rfile.readlines()[1:1001]
#    print lines
#    linevalues = lines.split(",")
#    firstval = float(linevalues[0])
#    secondval = float(linevalues[1])
#    print firstval, secondval

最后的东西只是如何解决它的想法。如果您执行脚本，您将看到第1000个坐标被粘贴到文件中，但是如何将lat / long / elevation的三个值分开并将它们按照google earth（long / lat / elevation）的必要顺序排列？我很乐意很快收到你的来信！感谢

编辑：现在它看起来像那样：

我需要它看起来像那样：

有一点不同：值49.xy（纬度）和8.xy（经度）也应该改变。

Answer 1

我建议只打开一次文件并编写所有内容，而不是多次打开和关闭。

问题是这一行： f.writelines(Koordinaten)

而不是这个，请使用：

f.write('\n'.join(Koordinaten))

使用python
