PyQGIS获取要素以及要素中的几何属性

from qgis.core import QgsProject,QgsVectorLayer

# 1、指定输入图层路径
path_to_airports_layer=r"E:\PyQGIS\Source_Data\Ex5\pt.shp"

# 2、图层格式
vlayer = QgsVectorLayer(path_to_airports_layer,"点位数据","ogr")

# 3、判断图层是否有效
if not vlayer.isValid():
    print("加载图层失败！")
else:
    QgsProject.instance().addMapLayer(vlayer)

features=vlayer.getFeatures()
for feature in features:
    geom=feature.geometry()
    id=feature.id()
    print(f"id:{id}, geom:{geom}")
