如何利用python批量读取多个json文件，并删除其中的重复点坐标？

1. json 的数据格式如下所示： { "type": "Feature", "properties": { "MC": null, "PWH": null, "SJ": "2015", "YDDM": "S41"}, "geometry": { "type": "MultiPolygon", "coordinates": [ [ [ [ 117.355254, 28.703052 ], [ 117.355254, 28.703052 ], [ 117.355250, 28.703018 ], [ 117.355246, 28.703002 ] ] ] } }
2. 可以看到，geometry中的coordinates中，第一项坐标和第二项坐标是重复的，现在的需求就是删除第二个（任意一个）重复的坐标，使得coordinates中没有重复的点。
3. 一个文件夹中有多个json，需要批量读取并删除。

c={ "type": "Feature", "properties": { "MC": null, "PWH": null, "SJ": "2015", "YDDM": "S41"}, "geometry": { "type": "MultiPolygon", "coordinates": [ [ [ [ 117.355254, 28.703052 ], [ 117.355254, 28.703052 ], [ 117.355250, 28.703018 ], [ 117.355246, 28.703002 ] ] ]] } }
c['geometry']['coordinates'][0][0]=c['geometry']['coordinates'][0][0][:1]+c['geometry']['coordinates'][0][0][2:]

你的坐标项搞那么多层次干嘛？很容易出错
