关于python 3.x：Unpickled对象与原始对象不匹配

Unpickled object does not match original

我的程序无法解开我的数据，其中pickle.load(f)与pickle.dump(object，f)不匹配。
我的问题是我在下面的代码中出错了，因为我已经尝试过各种各样的代码
我的代码上面列出了相应错误的文件模式：

f = open(home +'/。GMouseCfg'，'ab +')

出：他们是不同的

f = open(home +'/。GMouseCfg'，'ab +'，encoding ='utf-8')

ValueError：二进制模式不接受编码参数

f = open(home +'/。GMouseCfg'，'a +')

TypeError：必须是str，而不是字节

ids = [2,3,4,5,6,7,8,9,10,11,12]
home = expanduser('~')
f = open(home + '/.GMouseCfg','a+')
f.seek(0)

commands = list()
commands.append(KeyCommand({3:[e.KEY_RIGHTCTRL,e.KEY_P]}))
commands.append(SystemCommand({5:['gedit','./helloworld.txt']}))
pickle.dump(commands,f)
f.seek(0)
commands2 = pickle.load(f)
if commands == commands2:
print('They are the same')
else:
print('They are different')

我已经做了很多阅读python docs for pickles和file io但是我无法辨别为什么我的原始对象和未经修饰的对象之间存在差异

在酸洗和去除后，显然command和command2永远不会是同一个对象。

这意味着commands == commands2将始终返回False，除非您为您的类实现比较，例如：
