How can i stop this Infinite While Loop - Python

Wed Oct 30 07:55:15 EDT 2019

I have tried many ways to stop the infinite loop but my program doesn't seem to stop after 10 items! It keeps going...!)
---------------------------
total = 0 
while True: 
 print('Cost of item') 
 item = input() 
 if item != -1: 
 total += int(item) 
 else: 
 break 
print(total)
---------------------------
The output I am aiming for is for the code to stop asking 'Cost of item' after 10 inputs or until -1 is typed, but the code repeats itself on an infinite loop. I cannot seem to stop the infinite loop.
Thanks for any help in advance.
