Ah - bad explanation on my part. [apologies]<br>
I have the coordinates from a spreadsheet and I am busy making the
Point SHP (but wanting some attribute values from underlying
polygons)<br>

I'm doing my "once a year need to do something in python with QGIS" :-/
Using QGIS 3.38 and PyCharm.
I have a SHP file with 28000 polygons.
<strike>Another SHP</strike> <b><font color="#ff8040">spreadsheet</font></b> file with 22000 Points
Both in EPSG:4326
Without using QGIS processing, what is the quickest way to, for each
point 1 by 1, find the underlying polygon and read the attribute field
values of that polygon?
</blockquote>
Load it into postgis and write a select statement?
