Python multithreaded Programming Simple introduction _python

Creating Threads

Format is as follows

Copy Code code as follows:

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

This constructor must be invoked with a keyword pass parameter
-Group Thread groups
-Target Execution method
-Name thread names
-args target-executed tuple parameters
-Kwargs target-executed dictionary parameters

Thread Object function

Function description
Start () execution of the thread
Run () A function that defines the function of a thread (typically overridden by a quilt class)
The Join (Timeout=none) program hangs until the thread finishes, and if timeout is given, the maximum blocking timeout seconds
GetName () returns the name of the thread
SetName (name) sets the name of the thread
IsAlive () Boolean flag indicating whether this thread is still running
Isdaemon () returns the daemon flag of the thread
Setdaemon (daemonic) sets the thread's daemon flag to daemonic (must be called before the start () function is called)

Common examples

Format

Copy Code code as follows:

Import threading

def run (*arg, **karg):
Pass
Thread = Threading. Thread (target = run, name = "Default", args = (), Kwargs = {})
Thread.Start ()

Instance

Copy Code code as follows:

#!/usr/bin/python
#coding =utf-8

Import threading
From time import Ctime,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
For T in Threads:
T.join ()

Print "Game Over"

Output

Copy Code code as follows:

Sing start: (' Raise Me Up ',)
Dance Start: (' Rup ',)
Sing stop
Dance Stop
Game Over
