Trying to use python-nmap but receiving however python2 or 3 can't find PortScanner.

[snippsat]

./ip-get.py

Try not run script like this as it can unclear if it run in Python 2 or 3.
Here for scratch in eg Kail,as my Mint 19 i use pyenv | tutorial then there is no python3 or pip3.

# Test python 3
root@kali-tom:~# python3 -V
Python 3.7.5
root@kali-tom:~# which python3
/usr/bin/python3

# Test pip3
root@kali-tom:~# pip3 -V
pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)

# Install
root@kali-tom:~# pip3 install python-nmap
Collecting python-nmap
Installing collected packages: python-nmap
Successfully installed python-nmap-0.6.1

# Test that it work
root@kali-tom:~# python3
Python 3.7.5 (default, Oct 27 2019, 15:43:29) 
[GCC 9.2.1 20191022] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import nmap
>>> 
>>> nmap.PortScanner
<class 'nmap.nmap.PortScanner'>

# No error it works.
>>> nmap.PortScanner()
<nmap.nmap.PortScanner object at 0x7ff42e2ca6d0>
>>> exit()

Now that all work can run script with python3 ip-get.py.
