python - How to set up the ability to start peer instances of the application in Flask using PyCharm?

Question

I am building an flask API app for blockchain. I am creating multiple peer instances to communicate with the blockchain. I am assigning different ports by the following commands.

ROOT_PORT = 5000 PORT = ROOT_PORT

if os.environ.get('PEER') == 'True': PORT = random.randint(5001, 6000)

app.run(port=PORT)

Upon running in multiple command terminals using commands "python -m backend .app" and other peer with command "set PEER=True && python -m backend.app". The both peers run on the same port generating URL as: http://127.0.0.1:5000/. How to solve this issue?
