帮我生成一个控制2个电梯运行的python代码

好的，以下是一个控制2个电梯运行的Python代码：

class Elevator:
    def __init__(self, id):
        self.id = id
        self.current_floor = 1
        self.direction = 1
        self.destinations = []

    def add_destination(self, floor):
        if floor not in self.destinations:
            self.destinations.append(floor)
            self.destinations.sort()

    def move(self):
        if not self.destinations:
            return

        if self.current_floor == self.destinations[]:
            self.destinations.pop()

        if not self.destinations:
            return

        if self.current_floor < self.destinations[]:
            self.current_floor += 1
            self.direction = 1
        elif self.current_floor > self.destinations[]:
            self.current_floor -= 1
            self.direction = -1

class ElevatorController:
    def __init__(self):
        self.elevators = [Elevator(1), Elevator(2)]

    def request_elevator(self, floor):
        elevator = self._get_nearest_elevator(floor)
        elevator.add_destination(floor)
        return elevator.id

    def _get_nearest_elevator(self, floor):
        distances = []
        for elevator in self.elevators:
            if elevator.direction == 1 and floor >= elevator.current_floor:
                distances.append(floor - elevator.current_floor)
            elif elevator.direction == -1 and floor <= elevator.current_floor:
                distances.append(elevator.current_floor - floor)
            else:
                distances.append(abs(elevator.current_floor - floor))

        return self.elevators[distances.index(min(distances))]

    def step(self):
        for elevator in self.elevators:
            elevator.move()

这个代码实现了一个电梯控制器，可以控制两个电梯运行。你可以调用 `request_elevator` 方法来请求电梯，然后电梯会自动运行到你所在的楼层。你可以调用 `step` 方法来让电梯控制器运行一步，这样电梯就会移动到下一个目的地。
