      queue.pop(0)
      
queue = [ ]
while True :

            insert(City)
      elif user == "delete" :
            if queue == [ ]:
                  print("UnderFlow")
            else :
                  Delete(City)
      else :
            break
print("Now our Queue = ",queue)

Output :-

1 = For insert data Enter insert 
2 = For delete data enter delete 
3 = For Exit  enter exit 

Enter your choice :- insert
Enter City Name :- Path

Enter your choice as per given -
1 = For insert data Enter insert 
2 = For delete data enter delete 
3 = For Exit  enter exit 

Enter your choice :- insert

Enter your choice as per given -
1 = For insert data Enter insert 
2 = For delete data enter delete 
3 = For Exit  enter exit

Enter your choice as per given -
1 = For insert data Enter insert 
2 = For delete data enter delete 
3 = For Exit  enter exit
