Sharing variables between Python subprocesses

Question

I have a Python program named read.py which reads data from serial communication every second, and another python program called calculate.py which has to take the real time values from read.py.

Using subprocess.popen('read.py',shell=True) I am able to run read.py from calculate.py

May I know how to read or use the value from read.py in calculate.py? Since the value changes every second I am confused how to proceed like, saving value in registers or producer consumer type, etc.

for example : from import datetime when ever strftime %s is used, the second value is given how to use the same technique to use variable from another script?

Did you take a look at this and this?

I can suggest writing values to a .txt file for later reading
