Vulnerabilityscanner not working properly (Python)

[input54]

I follow a online course from Udemy and in one project i have to type the sourcecode myself.
But I receive an error :
Here is the code from portscanner.py

import socket
from IPy import IP

class PortScan():
    banners = []
    open_ports = []

    def __int__(self, target, port_num):
        self.target = target
        self.port_num = port_num


    def scan(self,):

        for port in range(1,500):
            self.scan_port(port)

    def check_ip(self, target):
        try:
            IP(self.target)
            return(self.target)
        except ValueError:
            return socket.gethostbyname(self.target)

    def scan_port(self,port):

        try:
            converted_ip = self.check_ip()
            sock = socket.socket()
            sock.settimeout(0.5)
            sock.connect((converted_ip, port))
            self.open_ports.append(port)

            try:
                banner = sock.recv(1024).decode().strip("\r")
                self.banners.append(banner)

            except:
                self.banners.append('')

            sock.close()

        except:
            pass

And here from vulscan.py:

import portscanner

targets_ip = input('[+] * Enter Target To Scan For Vulnerable Open Ports: ')
port_number = int(input('[+] * Enter Amount Of Ports You Want To Scan(500 - first 500 ports): '))
vul_file = input('[+] * Enter Path To The File With Vulnerable Softwares: ')
print('\n')

target = portscanner.Port(targets_ip, port_number)
target.scan()

with open(vul_file, 'r') as file:
    count = 0
    for banner in target.banners:
        file.seek(0)
        for line in file.readlines():
            if line.strip() in banner:
                print('[!!] VULNERABLE BANNER: "' + banner + '" ON PORT: ' + str(target.open_ports[count]))
        count += 1

The error is:
target = portscanner.PortScan(targets_ip,port_number)
^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'portscanner' has no attribute 'PortScan'. Did you mean: 'portscan'?
