how to multithread a function in python code example

Example 1: multithreading in python

from multiprocessing.pool import ThreadPool

def stringFunction(value):
    my_str = 3 + value
    return my_str


def stringFunctio(value):
    my_str = 33 + value
    return my_str



pool = ThreadPool(processes=1)

    
thread1 = pool.apply_async(stringFunction,(8,))
thread2 = pool.apply_async(stringFunctio,(8,))

return_val = thread1.get()
return_val1 = thread2.get()

Example 2: multithread python3

import timeimport threadingdef calc_square(number):   print("Calculate square numbers: ")   for i in numbers:      time.sleep(0.2)   #artificial time-delay      print('square: ', str(n*n))def calc_cude(number):   print("Calculate cude numbers: ")   for i in numbers:      time.sleep(0.2)      print('cube: ', str(n*n*n))arr = [2,3,8,9]t = time.time()t1 = threading.Thread(target = cal_square,args=(arr,))t2 = threading.Thread(target = cal_cube,args=(arr,))# creating two threads here t1 & t2t1.start()t2.start()# starting threads here parallelly by usign start function.t1.join()# this join() will wait until the cal_square() function is finised.t2.join()# this join() will wait unit the cal_cube() function is finised.print("Successed!")
