Elevator Simulator in Python.

Elevator Simulator in Python.

I need help with an elevator simulator in python and i dont have much
experience. There should be a user entered amount of customers that have
randomized start and destination floors. Right now im just coding the
simple strategy of the elevator going all the way to the top, and then
back to the bottom. When i run my code, the program infinitely loops. I
cant figure out why. Also, i'm not sure how to code my building's output
method, which i want to display which customers had which floors and how
many floors the elevator visited. Thanks for your help.
import random
class Elevator(object):
def __init__(self, num_of_floors, register_list, direction = "up",
cur_floor=1):
self.total_floors = num_of_floors
self.reg_list = register_list
self.floor = cur_floor
self.direct = direction
def move(self):
"""Moves the elevator one floor"""
if self.total_floors == self.floor:
self.direct = "down"
if self.direct == "up":
self.floor += 1
else:
self.floor -= 1
def register_customer(self, customer):
self.reg_list.append(customer)
def cancel_customer(self, customer):
self.reg_list.remove(customer)
class Building(object):
def __init__(self, num_of_floors, customer_list, elevator):
self.total_floors = num_of_floors
self.customers = customer_list
def run(self):
while elevator.floor != 0:
for customer in self.customers:
if elevator.floor == customer.on_floor:
elevator.reg_list.append(customer)
customer.indicator = 1
elif elevator.floor == customer.going_floor:
elevator.reg_list.remove(customer)
customer.indicator = 0
customer.fin = 1
elevator.move()
def output(self):
pass
class Customer(object):
def __init__(self, ID, num_of_floors, cur_floor=0, dst_floor=0,
in_elevator=0, finished=0):
self.ident = ID
self.indicator = in_elevator
self.fin = finished
cur_floor = random.randint(1, num_of_floors)
self.on_floor = cur_floor
dst_floor = random.randint(1, num_of_floors)
while dst_floor == cur_floor:
dst_floor = random.randint(1, num_of_floors)
self.going_floor = dst_floor
customer_count = int(input("How many customers are in the building?: "))
floor_count = int(input("How many floors does the building have?: "))
cus_list = []
for i in range(1, customer_count+1):
cus_list.append(Customer(i, floor_count))
elevator = Elevator(floor_count, cus_list)
building = Building(floor_count, cus_list, elevator)
