Question

我有一个家庭作业任务，这真的让我头疼。它涉及一个电梯模拟，需要用户输入楼层数和使用电梯的人数。人们的出发楼层和目的地楼层是楼层内的随机数字。

我认识到,我的法典非常稀少,存在一些差距,但我确实不知道从哪里走。

我需要在建筑类别内提供帮助,例如如何使(或)产出部分发挥作用。任何其他建议都会得到高度赞赏和帮助。请注意,我并不指望有人为我做法典,而是想把我的手交给我,告诉我什么路要走。班级似乎对我完全是神秘的。

import random

floors=raw_input( Please enter the number of floors for the simulation: )  
while floors.isalpha() or floors.isspace() or int(floors) <=0:  
    floors=raw_input( Please re enter a digit for number of floors: )  
customers=raw_input( Please enter the number of customers in the building: )  
while customers.isalpha() or customers.isspace() or int(customers) <0:  
    customers=raw_input( Please re enter a digit for number of customers: )  
count = 1  

class building:  
    def num_of_floors():    
        num_of_floors = floors      
    def customer_list():    
        customer_list = customers    
    def run(self):    
    def output(self):    
        print elevator.cur_floor    

class elevator:    
    def num_of_floors():    
        building.num_of_floors

    def cur_floor(customer):    
        cur_floor = random.randint(0,int(floors))    
    def dst_floor(customer):    
        dst_floor = random.randint(0,int(floors))    
        while dst_floor == cur_floor:    
            dst_floor = random.randint(0,int(floors))    
    def ID():    
        cust_id = count    
        count+=1    
    def cust_dict(cust_id,dst_floor):    
        cust_dict = {cust_id:dst_floor}    
    def in_elevator():    
        in_elevator = 0    
        if customer.ID in register_list:    
            in_elevator = 1    
    def finished():    
        if customer.ID not in register_list:

Answer 1

You need to understand the self parameter to all methods.
You need to understand __init__, the constructor.
You need to understand self.varible for your member variables.
You need to understand how to setup a main function.
You need to understand how to return a value from a function or method.
You need to understand how to assign to global variables from within a function or method.

Answer 2

或许你们的建筑阶层应该开始这样做。

class building:  
    def __init__(self, floors, customers):    
        self.num_of_floors = floors      
        self.customer_list = customers
        self.elevator = elevator()

Answer 3

您应在上花一定时间,即:Python Tutorial 或。

Answer 4

每一种方法的第一参数都是参照标的,通常称为自称。贵方需要参考对象。

第二,从一个类别内提及全球变量被认为是坏的。你们可以通过构造或参数把他们带给一个班子。
