attempted multithread doesn't multithread

[meems]

import threading,time

def simple_task(s):
      for j in range(5):
          print(s)
          time.sleep(0.5)

n=5
thread_list=[]

for i in range(n):
     t=threading.Thread(target=simple_task(i))
     t.start()
     thread_list.append(t)

expected result
 0,1,2,3,4,0,1,2....etc
actual
 0,0,0,0,0,1,1,1 etc

I've tried adding t.daemon=True, that doesn't change the result. I seem to be missing something. But haven't a clue what. Anyone know? thx
