我收到此错误：

ImportError: Could not find the GEOS library (tried ""geos_c"", ""libgeos_c-1"").  
Try setting GEOS_LIBRARY_PATH in your settings

当我跑步时：

from django.contrib.gis.geos import *
pnt=GEOSGeometry('POINT(23 5)')
print(pnt)

我加入GEOS_LIBRARY_PATH = 'C:/Python34/Lib/site-packages/osgeo/geos_c.dll'
了C:\Python34\Lib\site-packages\django\conf\project_template\project_name\settings.py

但我仍然遇到相同的错误。如何解决呢？

我有以下代码用于显示具有属性和数据表中的值的对象数组.但是这里的列标题是硬编码的,如下面的html代码所示.如何根据输入数据集使其动态化？

 var dataSet = [{
  "Latitude": 18.00,
  "Longitude": 23.00,
  "Name": "Pune"
}, {
  "Latitude": 14.00,
  "Longitude": 24.00,
  "Name": "Mumbai"
}, {
  "Latitude": 34.004654,
  "Longitude": -4.005465,
  "Name": "Delhi"
},{
  "Latitude": 23.004564,
  "Longitude": 23.007897,
  "Name": "Jaipur"
}];
$(document).ready(function() {
    $('#example').DataTable( {
        data: dataSet,
        "columns": [
            { "data": "Name" ,"title":"Custom Name"},
            { "data": "Latitude" },
            { "data": "Longitude" },

        ]
    } );
} );




<table id="example" class="display" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th>Name</th>
                <th>Latitude</th>
                <th>Longitude</th>

            </tr>
        </thead>

    </table>

在我的 Web 应用程序中，我使用的是传单，我想使用层切换将传单层更改为卫星视图和其他地图视图。我该如何执行此操作。请帮忙！

我想在每个之后展示一个空间*.我的代码是:

def stars(n):
    for x in reversed(range(n+1)):
            print x * '*'

我得到的输出是:

*****
****
***
**
*

但我想要:

* * * * *
* * * *
* * *
* *
*

另外,我想从右侧打印

* *
  *   

是否有任何方法可以从最后一个位置打印？
