I'm trying to use nmap in a python script. When I try to install it, it says that I already have nmap installed... So it should work in my python script right? But it's not working. I get this error when I try to use nmap in a script:

(I have "import nmap" at the top of the script)

"C:\Users\Mario\PycharmProjects\New Project 1\venv\Scripts\python.exe" "C:/Users/Mario/PycharmProjects/New Project 1/script.py"
