Introduction to Python multithreaded programming

Creating Threads

The format is as follows

Threading. Thread (Group=none, Target=none, Name=none, args= (), kwargs={})

This constructor must be called with the keyword argument
-Group Thread groups
-Target Execution method
-Name thread names
-Tuple parameters executed by the args target
-Dictionary parameters executed by Kwargs target

Thread Object functions

function	Description
Start ()	Start the execution of a thread
Run ()	Functions that define the functionality of a thread (typically overridden by a quilt class)
Join (Timeout=none)	The program hangs until the thread ends, and if timeout is given, it blocks timeout seconds
GetName ()	Returns the name of the thread
SetName (name)	Set the name of the thread
IsAlive ()	A Boolean flag that indicates whether the thread is still running
Isdaemon ()	Returns the daemon flag for a thread
Setdaemon (Daemonic)	Set the thread's daemon flag to Daemonic (be sure to call before the start () function is called)

Common examples

• Format

import threadingdef run(*arg, **karg):    pass"default", args = (), kwargs = {})thread.start()

• Instance

#!/usr/bin/python#coding =utf-8ImportThreading fromTimeImportCtime,sleep def sing(*arg):    Print "Sing start:", Arg sleep (1)Print "Sing Stop" def dance(*arg):    Print "Dance Start:", Arg sleep (1)Print "Dance Stop"Threads = []#创建线程对象T1 = Threading. Thread (target = sing, name =' Singthread ', args = (' Raise Me Up ',)) threads.append (t1) t2 = Threading. Thread (target = dance, name =' Dancethread ', args = (' Rup ',)) Threads.append (T2)#开始线程T1.start () T2.start ()#等待线程结束 forTinchThreads:t.join ()Print "Game Over"

Output

sing start:  (‘raise me up‘,)dance start:  (‘Rup‘,)stopstopgame over
