When I use While My program runs forever , even I gave A CONDITION (while ticket_remaining>=1:)

ticket_price=10 ticket_remaining=100 while ticket_remaining>=1: print("There are {} ticets rem. ".format(ticket_remaining)) name=input("What is your name? ") num_tickets=int(input("How many tick would ou like {} ? ".format(name))) amount_due=num_tickets*ticket_price print("The total due is {} $ ! ".format(amount_due)) should_proceed=input("Do you want to proceed? Y/N") if should_proceed.lower() =="y": print("SOLD!") ticket_remaining-=num_tickets else: print("Thank you anyways {}! ".format(name)) break if ticket_remaining==0: print("sorry ticket are all sold out")

My program run forever? Why is that?

Your program might have an indentation error, but it's impossible to check that in unformatted code.

Use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:
Or watch this video on code formatting.

ticket_price = 10 
ticket_remaining = 100 
while ticket_remaining >= 1 : 
      print("There are {} ticets rem. ".format(ticket_remaining)) 
      name = input("What is your name? ") 
      num_tickets = int(input("How many tick would ou like {} ? ".format(name))) 
      amount_due = num_tickets*ticket_price 
      print("The total due is {} $ ! ".format(amount_due)) 
      should_proceed = input("Do you want to proceed? Y/N") 
      if should_proceed.lower() == "y" : 
            print("SOLD!") 
            ticket_remaining -= num_tickets 
      else: 
            print("Thank you anyways {}! ".format(name)) 
      if ticket_remaining == 0: 
            print("sorry ticket are all sold out")

try without brake and make sure the spaces are properly set
