import time

# Method
def hello(name, t):
    time.sleep(t)
    print(f'Hello {name}')
    
# Parallel thread using a single processor core (use the same main core)
import threading
t = threading.Thread(target=hello, args=('Leo', 3))
t.start()
t.join()

# Parallel thread using a other than main processor core (for CPU intensive)
from multiprocessing import Process
p = Process(target=hello, args=('Leo', 5))
p.start()
p.join()
