Using ogrinfo in Python to find specified information

I am using ogrinfo in Python to find out information about a shapefile

from subprocess import Popen, PIPE
args = ['ogrinfo', '-so', '-al', 'C:/test/test_shapefile.shp']
process = Popen(args, stdout=PIPE, stderr=PIPE)
stdout = process.communicate()[0].decode('utf-8').strip()
print(stdout)

This obviously gives me a large summary, but I'm wondering is there any way to specify that I only want information regarding the extents or EPSG for example?

Is it mandatory for you to use the subprocess module? if not, there is a charming PyShp package for that. Also pay attention to this thread : https://gis.stackexchange.com/questions/113799/reading-shapefile-in-python – Taras Apr 26 '22 at 14:34
@Taras no it's not mandatory, it is just one of the first snippets of code I got working. I'll definitely look into PyShp - thank you! – fuzzy_raster9873 Apr 26 '22 at 15:02

GDAL is also a Python module, you can get file informations : https://pcjericks.github.io/py-gdalogr-cookbook/vector_layers.html#get-shapefile-feature-count – J. Monticolo Apr 26 '22 at 15:08
ogrinfo is a part of GDAL :) – fuzzy_raster9873 Apr 26 '22 at 15:12

Yes, I perfectly know, but it's also a Python module, so you can call it as from osgeo import gdal instead of call a subprocess. – J. Monticolo Apr 26 '22 at 15:24
