python 哪里有管理线程的需求？最好贴出来哪条数据处理出错了

python 哪里

此处做了判断，不确定是否为了避免重复执行 self._preprocess()，不过在代码中没有发现为 self.future_time 赋值的地方

我为此写了一个测试用例，可以复现我说的问题

from concurrent.futures import ThreadPoolExecutor
from unittest import TestCase

from jionlp import TimeParser


class TestJioNLP(TestCase):
    def setUp(self) -> None:
        self.parse_time = TimeParser()

    def test_thread_safe(self):
        with ThreadPoolExecutor(max_workers=5) as executor:
            futures = {executor.submit(self.parse_time, "2023年11月1日") for _ in range(5)}
            for future in futures:
                obj = future.result()
                self.assertEqual(obj['time'], ['2023-11-01 00:00:00', '2023-11-01 23:59:59'])

这个用例在执行的时候会得到如下错误

test_jionlp.py:8 (TestJioNLP.test_thread_safe)
self = <tests.test_jionlp.TestJioNLP testMethod=test_thread_safe>

    def test_thread_safe(self):

            futures = {executor.submit(self.parse_time, "2023年11月1日") for _ in range(5)}
            for future in futures:
>               obj = future.result()

哪能这么用，初始化是在初次调用 call 时候的。线程开启在__call__ 之前，初始化没做干净就开始解析，自然就报错了。
除非你手工执行 self.parse_time._preprocess() 函数
