- Then for the command part, we only use {d} command to delete every matching line found.

The following code is written in Python. It creates a variable that detects the current time. Then it loops through a range of numbers and chooses the last random number after 2 seconds. Finally, it prints that number to the screen. This function can be called countless times depending on the number of state lottery numbers needed.
import random
import time
start_time = time.time()
while time.time() - start_time < 2:
lottery_number = random.randint(0, 48)
print(lottery_number)
