If you need to run a for loop in parallel, then you can do one of the following:
Option 1 – Using multiprocessing
import multiprocessing
def sumall(value):
return sum(range(1, value + 1))
pool_obj = multiprocessing.Pool()
answer = pool_obj.map(sumall,range(0,5))
print(answer)
Option 2 – Using joblib module
from joblib import Parallel, delayed
import math
def sqrt_func(i, j):
time.sleep(1)
return math.sqrt(i**j)
Parallel(n_jobs=2)(delayed(sqrt_func)(i, j) for i in range(5) for j in range(2))
Option 3 – Using asyncio
import asyncio
import time
def background(f):
def wrapped(*args, **kwargs):
return asyncio.get_event_loop().run_in_executor(None, f, *args, **kwargs)
return wrapped
@background
def your_function(argument):
time.sleep(2)
print('function finished for '+str(argument))
for i in range(10):
your_function(i)
print('loop finished')
