How to constantly get data from a running program through cmd.exe?

Question

Python

Hey!
Here I have a program that I can run in python like this

import subprocess
subprocess.check_output("./stripe","listen")

And this program is constantly running, and constantly writes out data from the server.
I need to constantly receive this data, without turning off the process. THOSE. subprocess.check_output() writes out data only when the process ends, and I need to receive data without terminating the process.
Since it's done now (example above) doesn't give me real time data.

Answer 1

subprocess.Popen()
