用python的GUI帮我写一个端口扫描器

当然可以，您可以使用Python的Tkinter模块来创建GUI界面，使用socket模块来进行端口扫描。以下是一个简单的示例代码：

import tkinter as tk
import socket

def scan_ports():
    target = host_entry.get()
    start_port = int(start_port_entry.get())
    end_port = int(end_port_entry.get())

    for port in range(start_port, end_port+1):
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.settimeout(0.1)
        result = s.connect_ex((target, port))
        if result == 0:
            result_label.config(text=f"Port {port} is open")
        s.close()

root = tk.Tk()
root.title("Port Scanner")

host_label = tk.Label(root, text="Target Host:")
host_label.pack()
host_entry = tk.Entry(root)
host_entry.pack()

start_port_label = tk.Label(root, text="Start Port:")
start_port_label.pack()
start_port_entry = tk.Entry(root)
start_port_entry.pack()

end_port_label = tk.Label(root, text="End Port:")
end_port_label.pack()
end_port_entry = tk.Entry(root)
end_port_entry.pack()

scan_button = tk.Button(root, text="Scan Ports", command=scan_ports)
scan_button.pack()

result_label = tk.Label(root, text="")
result_label.pack()

root.mainloop()

您可以在GUI界面中输入目标主机、起始端口和结束端口，然后点击“Scan Ports”按钮进行扫描。扫描结果将会显示在界面上。请注意，这只是一个简单的示例代码，实际上需要更多的错误处理和优化。
