将部分 geojson 对象组合成另一个并拆分为 Python 中的键值对
Combine part of geojson object into another and split to key-value pairs in Python

到目前为止的解决方案，多亏了@dodopy 参考这里 ，我已经意识到结合 Point 和 LineString 得到以下结果：
import json
features = data["features"]
point_handle_text = {
i["properties"]["EntityHandle"]: i["properties"]["Text"]
for i in features
if i["geometry"]["type"] == "Point"
}
combine_features = []
for i in features:
if i["geometry"]["type"] == "LineString":
i["properties"]["Text"] = point_handle_text.get(i["properties"]["EntityHandle"])
combine_features.append(i)
data["features"] = combine_features
print(data)

是否可以在Python中获得预期的输出？谢谢。
我刚刚遍历了字典和列表。
本质上，如果缺少 "Text" 键，则使用 EntitiyHandle 并找到找到的 "Text" 值，然后将它们分开。然后将其摄取到没有 "Text" 键的元素中（如果有意义的话）：

到目前为止的解决方案，多亏了@dodopy 参考这里 Point 和 LineString 得到以下结果：
import json
features = data["features"]
point_handle_text = {
i["properties"]["EntityHandle"]: i["properties"]["Text"]
for i in features
if i["geometry"]["type"] == "Point"
}
combine_features = []
for i in features:
if i["geometry"]["type"] == "LineString":
i["properties"]["Text"] = point_handle_text.get(i["properties"]["EntityHandle"])
combine_features.append(i)
data["features"] = combine_features
print(data)

是否可以在Python中获得预期的输出？谢谢。
我刚刚遍历了字典和列表。
本质上，如果缺少 "Text" 键，则使用 EntitiyHandle 并找到找到的 "Text" 值，然后将它们分开。然后将其摄取到没有 "Text" 键的元素中（如果有意义的话）：
