循环将一个字典附加到另一个字典

我写了这段代码，我需要一些帮助对其进行调试。我不得不说，我已经在此网站上阅读了与此类似的主题，但是它无法帮助我调试代码:)

输出：

Number of max devices per route: 4
Number of routes: 2
Level of mobility: 2
routes  at T 0 : {0: [28, 14, 7, 4], 1: [22, 0]}
routes  at T 1 : {0: [29, 20, 28], 1: [28]}
{0: {0: [29, 20, 28], 1: [28]}, 1: {0: [29, 20, 28], 1: [28]}}

我的问题是我想有这样的输出：

{ 0:{0: [28, 14, 7, 4], 1: [22, 0]} , 1: {0: [29, 20, 28], 1: [28]},}

但是，我不知道为什么在新词典中再次重复最后一个词典。我尝试调试它，但无法成功。那么，如何在循环中将一个字典附加到另一个字典呢？

class myClassName(object):
    def __init__(self):
        """
        Class constructor.
        """

        self.no_devices = input("Number of max devices per route: ")
        self.no_routes = input("Number of routes: ")
        self.mob=input("Level of mobility: ")
        self.all_routes={}
        self.routes = {}

        self.arr = [0,1,2,3,4,5,6,7,8,9,10...,29] 

        for j in xrange(self.mob):
            for i in range(self.no_routes):
                random.shuffle(self.arr)                                          
                self.routes[i] = list(self.arr[0: random.randint(1,self.no_devices)])          
                self.all_routes[j]=self.routes


            print "routes  at T" ,j, ":" ,self.routes


        print self.all_routes

正如@shaktimaanself.routes在循环的每次迭代中指出的那样，该值将被覆盖，并且self.all_routes仅保留对的引用self.routes。我修改了代码，一次使其能够与python 3.4配合使用（即，我拥有python版本，对不起，我现在不使用2.x）并解决了覆盖问题。

import random

class myClassName(object):
    def __init__(self):
        """
        Class constructor.
        """

        self.no_devices = int(input("Number of max devices per route: "))
        self.no_routes = int(input("Number of routes: "))
        self.mob = int(input("Level of mobility: "))
        self.all_routes={}


        self.arr = list(range(0,30))

        for j in range(self.mob):
            routes = {}
            for i in range(self.no_routes):
                random.shuffle(self.arr)                                          
                routes[i] = list(self.arr[0: random.randint(1,self.no_devices)])          
                self.all_routes[j]=routes


            print("routes  at T" ,j, ":" ,routes)


        print(self.all_routes)



if __name__ == '__main__':
    myClassName()

输出示例：

Number of max devices per route: 4
Number of routes: 2
2Level of mobility: 
routes  at T 0 : {0: [0, 10], 1: [22, 14]}
routes  at T 1 : {0: [16], 1: [22, 3, 5, 17]}
{0: {0: [0, 10], 1: [22, 14]}, 1: {0: [16], 1: [22, 3, 5, 17]}}

希望这对您有用。
