auction()

I have a problem with this while loop in my function, it never stop. I try to change the value of the variable end_of_auction but is dosen’t work. then I tried to use the keyword break but is dosen’t work.

can someone please tell me what is the problem here and how can I end the loop?

>Solution :

The issue is that you are not calling the lower() method; instead, you store the method itself to the variable again. You can see that if you call print(again), as you get something resembling <built-in method lower of str object at 0x000002525EEA8030>.

Change the line to:

again = input('again ? (Yes or No) : ').lower()

All you other code seems like it should function as intended.
