1 threading.current().name

但是发现,同样的threading.current_thread()后面不仅仅有.name属性,而且还有.getName()方法.但是

这2个写法最后得出的结果却是一样的.

那么,2者区别在哪里呢?

代码语言:javascript复制
 1 import threading
 2 import time
 3 
 4 def run(arg):
 5     print("running sub thread...{}".format(threading.current_thread()))
 6     time.sleep(3)
 7 
 8 if __name__ == "__main__":
 9     t1 = threading.Thread(target=run,args=("t1",))
10     t1.start()
11     print("mian Thread...{}".format(threading.current_thread().getName()))
12     print("mian Thread...{}".format(threading.current_thread().name))
13 
14     t2 = threading.Thread()

定海偶然

name 是当前线程的属性, getName 是当前线程的方法。 尽管 threading.current_thread().name 和 threading.current_thread().getName() 的结果一样,但是完全不是同一种东西呀, 例如通过 threading.current_thread().name = ‘thread_python’ 来改变它。

最终演示代码:

代码语言:javascript复制
 1 import threading
 2 import time
 3 
 4 def run(arg):
 5     print("running sub thread...{}".format(threading.current_thread()))
 6     threading.current_thread().name="xurui_python"
 7     print("sub1 Thread...{}".format(threading.current_thread().getName()))
 8     print("sub2 Thread...{}".format(threading.current_thread().name))
 9     time.sleep(3)
10 
11 if __name__ == "__main__":
12     t1 = threading.Thread(target=run,args=("t1",))
13     t1.start()
14     print("mian1 Thread...{}".format(threading.current_thread().getName()))
15     print("mian2 Thread...{}".format(threading.current_thread().name))

演示代码

代码结果:

代码语言:javascript复制
1 running sub thread...<Thread(Thread-1, started 23296)>
2 mian1 Thread...MainThread
3 mian2 Thread...MainThread
4 sub1 Thread...xurui_python
5 sub2 Thread...xurui_python

代码结果
