generate random number non repeating with threading [closed]

import random,time
from threading import Thread
usleep = lambda x: time.sleep(x/1000000.0)


def getcode(numbers):
 data = '{"code":"'+ str(numbers) +'}'
 print(data)
 
 
 
inputNumbers =range(1,10)
randomize = random.sample(inputNumbers, 9)
THREAD_COUNT = 2
for numbers in randomize:
 for _ in range(THREAD_COUNT):               
  proc = Thread(target=getcode, args=[numbers])
  usleep(10000)
  proc.start()

i need to generate non repeating number from 1 to 10 with multithreading them . but it alwayes gives multiple same values duo to threading .
