How to run exe on client?

Question

Python

Good day.
Tell me if it is possible to run .exe on the machine from which the client came to the host. Let me explain: there is a code;

import os
class vnc():
def connect(ip):
os.system(r”путь до vnc “ %ip)

Now, when calling the function, vnc starts on the computer where the flask server started, but you actually need it to start on the computer that called the function.
I apologize for the unformatted code, it's not convenient from the phone.
