How to Use Python micro-threads in Stackless

We need to constantly learn how to use Python micro-threads, and some problems have been plaguing us. Let's take a detailed look at how to solve the technical problems and some tips. I hope you will have some gains.

Using Stackless Python's built-in module stackless can also complete multi-threaded programming, making it easier to use. The following S_P_C.py script will rewrite the code of the front-end producer and consumer to the Stackless version, the code is more concise.

 
 

  
  
#-*-Coding: UTF-8 -*-
  
  
# File: S_P_C.py
  
  
#
  
  
Import stackless # import stackless Module
  
  
Import Queue # import the Queue Module
  
  
Def Producer (I): # define the Producer
  
  
Global queue # declared as a global Queue object
  
  
Queue. put (I) # add data to the queue
  
  
Print 'producer ', I, 'add', I
  
  
Def Consumer (): # define a Consumer
  
  
Global queue
  
  
I = queue. get () # retrieve data from the queue
  
  
Print 'consumer', I, 'get', I
  
  
Queue = Queue. Queue () # generate a queue object
  
  
For I in range (10 ):
  
  
Stackless. tasklet (Producer) (I) # Add a Producer task
  
  
For I in range (10 ):
  
  
Stackless. tasklet (Consumer) () # Add a Consumer task
  
  
Stackless. run () # run the task
  
  
After the script is run, the output is as follows.
  
  
Producer 0 add 0
  
  
Producer 1 add 1
  
  
Producer 2 add 2
  
  
Producer 3 add 3
  
  
Producer 4 add 4
  
  
Producer 5 add 5
  
  
Producer 6 add 6
  
  
Producer 7 add 7
  
  
Producer 8 add 8
  
  
Producer 9 add 9
  
  
Consumer 0 get 0
  
  
Consumer 1 get 1
  
  
Consumer 2 get 2
  
  
Consumer 3 get 3
  
  
Consumer 4 get 4
  
  
Consumer 5 get 5
  
  
Consumer 6 get 6
  
  
Consumer 7 get 7
  
  
Consumer 8 get 8
  
  
Consumer 9 get 9
 
 

The above is an introduction to the Python micro-thread application. I hope you will get some benefits.
