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?
