如何在 Python 中获取线程 ID? [英] How to obtain a Thread id in Python?

问题描述

我有一个多线程 Python 程序和一个实用函数，writeLog(message)，它写出一个时间戳，然后是消息.不幸的是，生成的日志文件没有给出哪个线程正在生成哪个消息的指示.

I have a multi-threading Python program, and a utility function, writeLog(message), that writes out a timestamp followed by the message. Unfortunately, the resultant log file gives no indication of which thread is generating which message.

我希望 writeLog() 能够在消息中添加一些内容以识别哪个线程正在调用它.显然，我可以让线程传递这些信息，但这需要做更多的工作.是否有一些我可以使用的与 os.getpid() 等效的线程?

I would like writeLog() to be able to add something to the message to identify which thread is calling it. Obviously I could just make the threads pass this information in, but that would be a lot more work. Is there some thread equivalent of os.getpid() that I could use?

推荐答案

threading.get_ident() 有效，或 threading.current_thread().ident(或 threading.currentThread().ident 对于 Python <2.6).

threading.get_ident() works, or threading.current_thread().ident (or threading.currentThread().ident for Python < 2.6).
