pandas - 如何使用未识别的 feature.id 绘制带有 folium 和 geoJson 的 Choropleth 地图？

Question

我正在按照本指南从 Folium 绘制等值线图： https ://notebook.community/python-visualization/folium/examples/GeoJSON_and_choropleth

from branca.colormap import linear

colormap = linear.OrRd_03.scale(
    ecuador['Confirmed cases'].min(),
    ecuador['Confirmed cases'].max())

ecuador_dict=ecuador.set_index('Provinces')['Confirmed cases']

fec_map= folium.Map(zoom_start=6, tiles="OpenStreetMap", control_scale=True, location=[latitude_ec, longitude_ec])
folium.GeoJson(geojson_ec,
               name='Confirmed cases',
               style_function=lambda feature: {
                'fillColor'= colormap(ecuador_dict[features['properties.dpa_despro']]),
                'color': 'black',
                'weight': 2,
                'dashArray': '5, 5'}
                ).add_to(fec_map)
fec_map

地理JSON：

geojson_ec = {'type': 'FeatureCollection',
        'features': [{'type': 'Feature',
                      'properties': {'id_prov': 1,

                                     }}]}

但是，我收到此错误：

File "<ipython-input-131-1cdbb903e2f9>", line 7
    'fillColor'= colormap(ecuador_dict[features['properties.dpa_despro']]),
               ^
SyntaxError: invalid syntax

请帮助我理解指南并设置正确的颜色图。

-r-beginners 提出的解决方案：

fec_map= folium.Map(zoom_start=6, tiles="OpenStreetMap", control_scale=True, location=[latitude_ec, longitude_ec])
folium.GeoJson(geojson_ec,
               name='Confirmed cases',
               style_function=lambda feature: {
                'fillColor'= ecuador_dict[feature['properties']['dpa_despro']],
                'color': 'black',
                'weight': 2,
                'dashArray': '5, 5'}
                ).add_to(fec_map)
fec_map

结果：
