QGIS Python (PyQGIS) - Measure distance between features

Use the QGIS Python API (PyQGIS API) to measure the distance between features. This tutorial will cover how to measure the distance between features in the same layer and features in different layers. It covers measuring distance between specific features and all the features in multiple layers. Expand and advance you geospatial analysis by automating tasks with the QGIS Python API.

I am trying to add all polygon that are under the radius(300m) of my selection polygon, do you have any tutorial for that ? thank you very much

You can buffer the polygon of interest by 300 m, then find all the polygons that intersect the buffer

what can i do to measure the distance of two features using ellipsoidal measuring. my project use WGS84 ellispoid. so, the measuring of the functions distance() is very different of the measuring i do manually. can you help me ? thank you very much

This question/answer should help you get what you want. gis.stackexchange.com/questions/207942/qgis-python-distance-between-points

@@geospatialschool I had already see that. So the idea is to use the processing algorithm that create points around the polygons and use the code on that link to return the more closest? Can you tell me if the distance functions use this way to return the closest distance between the two polygons?

My loop does not work, only the first line appears, despite having the same code
