multiprocessing with Pool using different functions...

from time import sleep
from multiprocessing import Pool


def func1(data):
    sleep(4)
    print('Func1 done')
    return 42

def func2(data):
    sleep(3)
    print('Func2 done')
    return 13

def func3(data):
    sleep(2)
    print('Func3 done')
    return 21

functions = [func1, func2, func3]

data = [1,2,3,4]

def worker(args):
    func, data = args
    return func(data)


work_to_do = [(f, data) for f in functions]
pool = Pool(2)
result = pool.map(worker, work_to_do)

print(result)
