this is where you should use subprocess.Popen or subprocess.call rather than subprocess.run

subprocess.call will be a blocking call, which mean it wait until the command finish and then it will move on with your code.

or another way is to put your subprocess.run in an async function and execute it separately

example

import asyncio
async def run_nmap(ip:str):
    subprocess.run(["nmap", ip])

def run_the_thing():
    ...
    loop = asyncio.get_event_loop()
    loop.create_task(run_nmap("192.168.1.1"))
    ...

You can make subprocess in try / except:

try:
    subprocess.run(["nmap", "192.168.1.1"])
except:
    print("Nmap Stopped.")
    pass

When you press CTRL+C an error will be occur and you handle it with except section.
