execute export command to current terminal using python

Question

I want to set environment in current terminal using python. I have tried below method but they all are executing in subterminal.

Ex 1 - export OpenCV_DIR=/home/root/cv_install/share/OpenCV/

I tried::
a) os.environ['OpenCV_DIR'] = "/home/root/cv_install/share/OpenCV/"
b) subprocess.run("export OpenCV_DIR=/home/root/cv_install/share/OpenCV/", shell=True)
c) os.system("export OpenCV_DIR=/home/root/cv_install/share/OpenCV/", shell=True)

None of the above listed method worked for me. Can anyone help me out.
