What is multiprocessing,

Different between multiprocessing and multithreading,

Let’s see multiprocessing in action,

def long_running_function():
time.sleep(10)
return
for _ in range(0, 10):
long_running_function()
import multiprocessing
_process = multiprocessing.Process(target=long_running_function, args=())
_process.start()
for _ in range(0, 10):
_process = multiprocessing.Process(target=long_running_function, args=())
_process.start()
_processes = []for _ in range(0, 10):
_process = multiprocessing.Process(target=long_running_function, args=())
_process.start()
_processes.append(_process)
for _process in _processes:
_process.join()
import multiprocessing
import timedef long_running_function():
time.sleep(10)
return_processes = []for _ in range(0, 10):
_process = multiprocessing.Process(target=long_running_function, args=())
_process.start()
_processes.append(_process)for _process in _processes:
_process.join()
