for port in range(port_range[0], port_range[1] + 1):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(1)
result = sock.connect_ex((target, port))
if result == 0:
print(f"Port {port} is open")
sock.close()
target = "example.com"
port_range = (1, 1024)
port_scan(target, port_range)This script demonstrates how a basic port scanner can be implemented, which is a common tool used in ethical hacking to identify open ports on a target system.
