python threading.current_thread().name和.getName()有什么区别

今天学到python多线程这块,想显示当前线程是主线程还是子线程.网上一搜,有个方法叫

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?

import threading
import time

def run(arg):
    print("running sub thread...{}".format(threading.current_thread()))
    time.sleep(3)

if __name__ == "__main__":
    t1 = threading.Thread(target=run,args=("t1",))
    t1.start()
    print("mian Thread...{}".format(threading.current_thread().getName()))
    print("mian Thread...{}".format(threading.current_thread().name))

    t2 = threading.Thread()

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:

import threading
import time

def run(arg):
    print("running sub thread...{}".format(threading.current_thread()))
    threading.current_thread().name="xurui_python"
    print("sub1 Thread...{}".format(threading.current_thread().getName()))
    print("sub2 Thread...{}".format(threading.current_thread().name))
    time.sleep(3)

if __name__ == "__main__":
    t1 = threading.Thread(target=run,args=("t1",))
    t1.start()
    print("mian1 Thread...{}".format(threading.current_thread().getName()))
    print("mian2 Thread...{}".format(threading.current_thread().name))

 代码结果:

running sub thread...<Thread(Thread-1, started 23296)>
mian1 Thread...MainThread
mian2 Thread...MainThread
sub1 Thread...xurui_python
sub2 Thread...xurui_python
