How to use threading in Python?

Question

I am trying to understand threading in Python. I've looked at the documentation and examples, but quite frankly, many examples are overly sophisticated and I'm having trouble understanding them.How do you clearly show tasks being divided for multi-threading?

Answer 1

In Python 3:

>> import multiprocessing

r = range(0,10)

def Func(x):

r = x + 1

return x

P = multiprocessing.Pool(5)

allResult = P.map(Func, r)

allResult will contain a list of all the result.

In this example, I have created a range(0,10) but you can create a list. And Func named Function, which will take 1 parameter and does the task and return the value. All the values are in allResult variable.

To do a simple multi-threading you should always have a function which take atleast 1 parameter and have a list as of input.
