将下列java代码改为python代码：blic static void scan(String host, int startPort, int endPort) throws InterruptedException { List<Integer> portList = new ArrayList<>(); final CountDownLatch latch = new CountDownLatch(endPort - startPort + 1); for (int port = startPort; port <= endPort; port++) { int finalPort = port; Thread thread = new Thread(new Runnable() { @Override public void run() { try { Socket socket = new Socket(); socket.connect(new InetSocketAddress(host, finalPort), 100); System.out.println("TCP端口" + finalPort + "开放"); portList.add(finalPort); } catch (Exception e) { } try { DatagramSocket dsocket = new DatagramSocket(finalPort); dsocket.close(); } catch (SocketException e) { portList.add(finalPort); System.out.println("UDP端口" + finalPort + "开放"); } latch.countDown(); } }); thread.start(); } latch.await(); portList.sort(new Comparator<Integer>() { @Override public int compare(Integer o1, Integer o2) { return o1.compareTo(o2); } }); }

由于Python是一种解释型语言，因此需要使用不同的模块和语言结构来实现相同的功能。以下是一个类似的Python代码：

import socket
import threading

def scan(host, startPort, endPort):
portList = []
lock = threading.Lock()

def checkPort(port):
try:
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(0.1)
result = sock.connect((host, port))
with lock:
portList.append(port)
print("TCP端口" + str(port) + "开放")
sock.close()
except:
pass

try:
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.settimeout(0.1)
sock.bind((host, port))
with lock:
portList.append(port)
print("UDP端口" + str(port) + "开放")
sock.close()
except:
pass

threads = []
for port in range(startPort, endPort+1):
t = threading.Thread(target=checkPort, args=(port,))
threads.append(t)
t.start()

for t in threads:
t.join()

portList.sort()
return portList

# 示例
if __name__ == "__main__":
host = "127.0.0.1"
startPort = 1
endPort = 65535
openPorts = scan(host, startPort, endPort)
print(openPorts)
