如何在python中使用多线程将数据写入文本文件？

import threading

class WriteThread(threading.Thread):
    def __init__(self, data, file):
        threading.Thread.__init__(self)
        self.data = data
        self.file = file

    def run(self):
        with open(self.file, 'a') as f:
            f.write(self.data + '\n')

data_list = ['data1', 'data2', 'data3']  # 数据列表
file_path = 'output.txt'  # 文件路径

threads = []
for data in data_list:
    thread = WriteThread(data, file_path)
    thread.start()
    threads.append(thread)

# 等待所有线程执行完毕
for thread in threads:
    thread.join()
