In your code you haven't defined the variable <code>f</code> which should reference the file-object you want to write to. You could either do

<pre><code>f = open("KML.txt", "w")
f.write("&lt;KML_File&gt;\n")
...
f.close()
</code></pre>

or better:

<pre><code>with open("KML.txt", "w") as f:
 f.write("&lt;KML_File&gt;\n")
 ...
</code></pre>

which makes sure to always close the file even if some code in between fails.

For writing XML-files you might want to take a look at the Python <a href="https://docs.python.org/2/library/xml.html#module-xml" rel="nofollow noreferrer">xml-package</a>.

Hard-coding XML output to create a KML file in a series of print statements can be error-prone and hard to maintain. Rather use a Python KML library such as <a href="http://simplekml.readthedocs.io/en/latest/" rel="nofollow noreferrer">simplekml</a> or <a href="https://pythonhosted.org/pykml/" rel="nofollow noreferrer">pyKML</a> to generate the KML. The simplekml API simplifies writing KML and also produces valid KML with code that is cleaner and easier to understand.
<pre class="lang-py prettyprint-override"><code>import simplekml

# list2 = ...some assignment with list of point data elements
kml = simplekml.Kml()
for row in list2:
 kml.newpoint(description=row[0],
 coords=[(row[2], row[1])]) # lon, lat, optional height
 kml.save(&quot;test.kml&quot;)
</code></pre>
Using this test input for a single point:
<pre><code>list2 = [ [ 'description', 51.500152, -0.126236 ] ] # description, lat, lon
</code></pre>
The KML output would be this:
<pre class="lang-xml prettyprint-override"><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;kml xmlns=&quot;http://www.opengis.net/kml/2.2&quot; xmlns:gx=&quot;http://www.google.com/kml/ext/2.2&quot;&gt;
 &lt;Document id=&quot;feat_1&quot;&gt;
 &lt;Placemark id=&quot;feat_2&quot;&gt;
 &lt;description&gt;description&lt;/description&gt;
 &lt;Point id=&quot;geom_0&quot;&gt;
 &lt;coordinates&gt;-0.126236,51.500152,0.0&lt;/coordinates&gt;
 &lt;/Point&gt;
 &lt;/Placemark&gt;
 &lt;/Document&gt;
&lt;/kml&gt;
</code></pre>

I'm still very new to python, i am trying to export the locations on a list (List2) into a kml file which will then display the results on google maps. I have no idea really what i am doing and atm all i am getting is a syntax error around every ,", symbol. Can someone help me with this please.

<pre><code>KMLFile = open("KML.txt", "w")
f.write("&lt;KML_File&gt;\n")
f.write("&lt;Document&gt;\n")
for line in List2:
 f.write(" &lt;Placemark&gt;")
 f.write(" &lt;decription&gt;" + str(row[0]) + "&lt;/description&gt;")
 f.write(" &lt;Point&gt;")
 f.write(" &lt;coordinates&gt;" + str(row[2]) + str(row[1])"&lt;/coordinates&gt;")
 f.write(" &lt;/Point&gt;")
 f.write(" &lt;/Placemark&gt;")
f.write("&lt;/Document&gt;\n")
f.write("&lt;/kml&gt;\n")
KMLFile = close()
</code></pre>

Trying to make a KML file in Python

Python

我仍然是python的新手，我正在尝试将列表上的位置(List2)导出到一个kml文件中，该文件将在谷歌地图上显示结果。我真的不知道我在做什么，atm所有我得到的都是一个语法错误周围的每个，"，符号。有人能帮助我吗？KMLFile = open("KML.txt", "w")f.write("<KML_File>\n"...
