python - Add result from multiprocessing into array

I have a problem in when using results from multiprocessing in Python:

worker = math.ceil(lenRes1/maxRecord)
print(worker)
p=multiprocessing.Pool(worker)
while i < len(res):
    if(maxRecord > len(res)):
        t1arg = res[i:maxRecord]
    else:
        t1arg = res[i:maxRecord]
    #print(str(worker) + str(i) + str(lenRes1) + str(maxRecord))
    result = p.starmap_async(insertSingleObl.joinRes,[(t1arg,str(th),resJoinCorCustomer)])
    resFin.append(result.get)
    #p.start()
    i += RecordProcess
    maxRecord += RecordProcess
    th += 1
p.close()
p.join()

When I want to use it in a function, the list becomes:

[[array([[None, '010200189217', '010200189217', ..., None, None, '36'],

IndexError: list index out of range

It's because I need to run line-by-line:

for line in resFin:
  xxxx

Can someone help me with this problem? The problem is I need to append the result from each thread into one list.
