如何将Python 3.4输入信息导出到JSON？

Question

我正在尝试构建一个人工智能程序，该程序将跟踪信息和其他内容，但在试图将信息导出到文件时遇到问题。我是Python的新手，希望能够帮助确定可能存在的问题。

这里是源代码。

#Importations 
import jsonpickle 
import math 
import os 
import sys 
import time 
from random import randrange, uniform 
#Setups 
SAVEGAME_FILENAME = 'aisetup.json' 
game_state = dict() 
#Program AI 
class Computer(object): 
    def __init__(self, name, creator): 
     self.name = name 
     self.creator = creator 
#User Information 
class Human(object): 
    def __init__(self, name, birth): 
     self.name = name 
     self.birth = birth  
#Load Program Save 
def load_game(): 
    """Load game state from a predefined savegame location and return the 
    game state contained in that savegame. 
    """ 
    with open(SAVEGAME_FILENAME, 'r') as savegame: 
     state = jsonpickle.decode(savegame.read()) 
    return state 
#Save Program to JSON 
def save_game(): 
    """Save the current game state to a savegame in a predefined location. 
    """ 
    global game_state 
    with open(SAVEGAME_FILENAME, 'w') as savegame: 
     savegame.write(jsonpickle.encode(game_state)) 
#Initialize Program 
def initialize_game(): 
    """Runs if no AISave is found""" 
    UserProg = Human('User', '0/0/0') 
    AISystem = Computer('TempAI', 'Austin Hargis') 

    state = dict() 
    state['UserProg'] = [UserProg] 
    state['AISystem'] = [AISystem] 
    return state 
#TextPad 
#Main Code - Runs Multiple Times per Being Openned 
def prog_loop(): 
    global game_state 
    name = input (str("What is your name?: ")) 
    save_game() 

#Main Program 
def main(): 
    """Main function. Check if a savegame exists, and if so, load it. Otherwise 
    initialize the game state with defaults. Finally, start the game. 
    """ 
    global game_state 

    if not os.path.isfile(SAVEGAME_FILENAME): 
     game_state = initialize_game() 
    else: 
     game_state = load_game() 
    prog_loop() 
#Launch Code 
if __name__ == '__main__': 
    main() 

我每次运行它，它导出的信息保存到文件是这样的：

{"UserProg": [{"birth": "0/0/0", "py/object": "__main__.Human", "name": "User"}], "AISystem": [{"py/object": "__main__.Computer", "name": "TempAI", "creator": "Austin Hargis"}]} 

我希望它你的名字导出到文件夹，但它不工作的权利。

你永远不做任何与用户输入的名称：

def prog_loop(): 
    global game_state 
    name = input (str("What is your name?: ")) 
    save_game() 

name仅仅是一个局部变量存在。如果你想将它保存为名字的人，那么你需要设置在UserProg进入你的游戏状态：

def prog_loop(): 
    name = input("What is your name?: ") 
    # game_state['UserProg'] is a list with one Human instance in it 
    game_state['UserProg'][0].name = name 
    save_game() 

因为你改变可变对象包含在game_state而不是分配到game_state本身，您不需要global声明那里。 str()调用也是多余的，"..."语法已经产生了一个字符串，将它转换为字符串再次没有多大意义。
