python threading.current_thread().name和.getName()有什麼區別

今天學到python多線程這塊,想顯示當前線程是主線程仍是子線程.網上一搜,有個方法叫

1 threading.current().name

定海偶然

可是發現,一樣的threading.current_thread()後面不單單有.name屬性,並且還有.getName()方法.可是

這2個寫法最後得出的結果倒是同樣的.

那麼,2者區別在哪裏呢?

 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 是當前線程的屬性， getName 是當前線程的方法。
儘管 threading.current_thread().name 和 threading.current_thread().getName() 的結果同樣，可是徹底不是同一種東西呀， 例如經過 threading.current_thread().name ＝ 'thread_python' 來改變它。

最終演示代碼:

 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))

演示代碼

 代碼結果:

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

代碼結果
