Catching process stdout from another python script

Question

I have launched popen task ''' p = subprocess.Popen(['nmap', '-', '-oX', '192.168.19.159'], stdout=subprocess.PIPE) '''

In cmd tasklist command i can see pid of the laucnhed process ()

Can i create new python script, from which i can connect to my launched process by pid and get stdout from launched process?

I tried libraries psutil,subprocess. But i did not find answer.

The documentation: https://docs.python.org/3/library/subprocess.html

It tells that the returned object of Popen provides stdout and stderr as fields for the captured output. You should be able to iterate over those lines.

It's not clear how you intend to use it. A python file that does create a process can capture its output as mentioned. What do you want to do with another python file?
