multithreading in python - hackejima - 09-28-2014

i have learn to use multithreading in c/c++ but i couldn't get through using it in python or how to use it. Can someone help me on that please or recommend a tutorial or white paper on threading in python . All i have notice on it from several codes is using an instance of the thread module as argument to a class as in "class run(thread.Threading):". Am using python 2.7 win32, any help is appreciated.

Hello sir, your question meets my interests. I would like to try help you. This is a sample run of a very basic example of multithreading script I just wrote now to show you.

Spoiler: <span style="font-weight: bold;" class="mycode_b">Code</span>Code:
## Importing
from threading import Thread

## Setting a list to gather the threads for joining
thread_list = []

## Function to use with each thread
def func(x, y):
    print "{} + {} = {}".format(x, y, x+y)

## General loop
for item in ((1, 2), (3, 4), (5, 6), (7, 8), (9, 10)):
    ## Thread Proper Implementation
    thread = Thread(target=func, args=((item[0], item[1], )))
    ## Making each thread daemonic so they will be able to run
    ## on the background without affecting surely the main program
    ## execution
    thread.daemon = True
    ## Start the each thread
    thread.start()
    ## Put it to the list
    thread_list.append(thread)

## Wait till all the threads are done
for thread in thread_list:
    thread.join()

I hope this helped out a little, if anything more you want to know or generally anything you would like to ask me please feel free doing it!
Kind Regards.

Thanks very much pyscho_coder and LoaD1nG. the code was very helpful especially the links, it was guiding. Thanks for the help.

You are very welcome, also make sure you put the '@' simbol before you mention a member's name so we get a notification that you mentioned us and we respond as fast as possible.

Like this @hackejima .
Cheers!

NOTE: the 'o' in my name is a zero just to let you know for further mentioning in any case.
