python - Problems with shared memory with multiprocessing.Pool

Question

I wrote a program in order to learn how to manage shared memory:

import time 
from multiprocessing import Pool, Value

def increment_counter(counter):
   print(f'Executing')
   with counter.lock:
       counter.value +=1
       print(f'{counter.value}')
       time.sleep(0.1)

if __name__ == "__main__":

   counter = Value('i', 0)

   pool = Pool(processes=7)
   while counter.value < 100:
       pool.apply_async(increment_counter,(counter))

It never executes the function, in fact it never print 'Executing'.
