[Python] expect: make two python scripts communicate

I want to have two scripts communicating by exchanging messages. I have to use pexpect because of other restrictions. I am trying to make a minimal working example before I build it out for my application.

I have tried to do a minimal working example by following the tutorials I could find on the internet. But I've failed and here is my attempt.The first script is the one that initiates communication:

#script_1.py

import pexpect

p = pexpect.spawn("python /path/to/script/script_2.py")
p.expect(">")
p.sendline(input("Message to the other script: "))
print( p.before )


Here is the second script which should receive communication and send answer:

#script_2.py

indata = input(">")
print(indata)


How can I make two python scripts communicate by using pexpect?


EDIT: I was asked why I say that the scripts fail given that there are no error messages. The reason it is a failure is that script 2 should echo the message sent by script 1, and script 1 should print out (or in other ways capture the response), but that doesn't happen
