The threading in Python

Import threading, Time

#新线程执行的代码:

def loop ():

Print (' thread%s is running ... '% threading.current_thread (). Name)

n = 0

While n < 5:

n = n + 1

Print (' thread%s '% Threading.current_thread (). Name)

Time.sleep (3)

Print (' thread%s ended. '% Threading.current_thread (). Name)

Print (' thread%s is running ... '% threading.current_thread (). Name)

t = Threading. Thread (Target=loop, name= ' Loopthread ')

T.start ()

#t. Join ()

Print (' thread%s ended. '% Threading.current_thread (). Name)

Execution Result:

Thread Mainthread is running ...

Thread Loopthread is Running...thread Mainthread ended.

Thread Loopthread

Thread Loopthread

Thread Loopthread

Thread Loopthread

Thread Loopthread

Thread Loopthread ended.

Child threads are created in the main thread, and the main thread and child threads run in parallel

def go (name):

Time.sleep (1)

For j in Range (20):

T1 = Threading. Thread (Group=none, Target=go, Name=none, Args= (J,))

T1.start ()

For I in range (20):

Go (i)

J is parallel execution, the main thread and 20 sub-lines are executed in parallel

I is serial execution, only the main thread

T2 = Threading. Thread (Group=none, Target=con, Name=none, kwargs={' name ': ' Yuangong '})

T1.start ()

T2.start ()

Two threads interact in parallel, taking data in one queue
