My vip variable does not take False as a value and always defaults to True

Below is the code to return either a VIP customer or an ordinary customer, the list does not take vip as a False value and always takes True.

Class DonutQueue():      def arrive(self,name,VIP):            self.name = name          self.vip = VIP          if self.vip==True:              self.queue2.append(self.name)              return self.queue2          else:              self.queue.append(self.name)              return self.queue          def next_customer(self):            while not self.queue2== []:              if not self.queue2==[]:                  return self.queue              else:                  return self.queue2    def main():        n = int(input("Enter the number of customers you want to add"))      for i in range(0,n):          name = input("Enter their name")          vip= bool(input("Are they a VIP"))          DonutQueue.arrive(name,VIP)      print (DonutQueue().next_customer())  

Below is the output:

Enter the number of customers you want to add2  Enter their name John  Are they a VIP False  Enter their name Wick  Are they a VIP True  None  

Why am I getting None as the output and my value always takes True when I input False.

Below is the debugger values:

i:0  n:2  name: John  vip: True
