How to organize interactive data exchange (i / o) between the gdb console and the control python script?

Question

Python

Good afternoon. It is required to organize a control module that writes data to gdb and reads the reaction. Different commands are generated for gdb depending on the console response.
The essence of the task is the automation of debugging. Feature - unfortunately, this is needed under Windows.
Python is not the main language, I tried async subprocess, something did not take off.
Please point me in the right direction :)

Answer 1

p = subprocess.Popen('gdb.exe',
                 stdout=subprocess.PIPE,
                 stderr=subprocess.PIPE,
                 stdin=subprocess.PIPE)

while not p.poll(): # щупает процесс на предмет кода завершения, если кода нет - возвращает None
    print(p.stdout.readline()) # будет ждать целую строку из stdout
    p.stdin.write(b'testbytes') # напишет в stdin
