完全迷失了如何实现保存/加载功能（初学者！）

我的完整游戏代码在下面，我需要添加一个保存加载功能，我知道它会发生类似的事情

dct = {'hp': 0,'gold': 100} #<- state

import json

json.dump(dct,open("savegame.json","w"),indent=4) #SAVING

但是我不知道将其放在代码中或如何执行。我的老师没有解决这个问题，所以初学者的提示会很棒。请帮忙。谢谢。

大量代码！学习是好的。

似乎您只想将'load'和'save'添加到process_command（）。您可能需要类似以下代码：

     if chosen_command == 'save':
        with open('game.json','w') as the_file:
            json.dump(the_player,the_file)
     elif chosen_command == 'load':
        with open('game.json','r') as the_file:
            the_player = json.load(the_file)

继续黑客！记笔记！

这里没有尝试在很大程度上重构代码的一些通用功能，您可以将代码添加到想要的代码中。

好运。
