在我非常简单的情况下，我想显示pointsGeoJSON 文件中点的热图，但不显示地理密度（纬度、经度）。文件中points每个点都有一个confidence属性（0到1之间的值），如何根据该参数显示热图？weight=points.confidence似乎不起作用。

举个例子：

#points.geojson\n{\n"type": "FeatureCollection",\n"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },\n"features": [\n{ "type": "Feature", "properties": {"confidence": 0.67}, "geometry": { "type": "Point", "coordinates": [ 37.703471404215918, 26.541625492300192 ] } },\n{ "type": "Feature", "properties": {"confidence": 0.76}, "geometry": { "type": "Point", "coordinates": [ 37.009744331225093, 26.710090585532761 ] } },\n{ "type": "Feature", "properties": {"confidence": 0.94}, "geometry": { "type": "Point", "coordinates": [ 37.541708538306224, 26.160111944646022 ] } },\n{ "type": "Feature", "properties": {"confidence": 0.52}, …

我有一本字典和一个值列表，例如：

dictionary = {'a': 1, 'b': 2, 'c': 3, 'd': 4}

liste = [2, 3]

我想：

result = ['b', 'c']

如果我有一本非常大的字典，那么最好的方法是什么？

键具有唯一值。
