封装好的函数

    dict_key_ls = list(dicts.keys())#取键值keys，转化为list才能shuffle
    random.shuffle(dict_key_ls)
    new_dic = {}                    #创建空字典
    for key in dict_key_ls:
        new_dic[key] = dicts.get(key)#打乱后的key对应的value 赋值给空字典，结果有一位小数   ##一定是key？？ 
    return new_dic      
print(random_dic(dictName))        




arrxx=[1.0, 8.0, 4.0, 1.0, 1.0, 2.0, 8.0, 5.0, 2.0]
def intList(arr):  #list里面的元素转化为整数================#
    arr_temporary=[]

        arr_temporary.append(item)
    return(arr_temporary)
