Communication between console of two programs - Python

Question

Good night Need to do through python communication between two programs, the second does not need to be in python, as it is just an example

I have the following code

print('Qual seu nome?')
x = input()
print('Seu nome é: ' + x)

How can I get another program to answer his question without changing his code? I need another open program to send the information.

I need to do this communication in Python, but the program that will receive the information will not necessarily be written in python.

Basically this:

But without changing the code of the original program
