python - 如何将 json 序列化字典恢复为原始对象形式

Question

因此，我试图将一个对象保存到一个 json 文件中，然后将该对象恢复为允许我调用其函数的状态。例如，

listofobjects = [<object>, <object>]
json.dump(listofobjects.to_json(), 'file.json') #to_json is a function within the package I'm using to get the object in question to an object
file = open("file.json", "r")

contents = file.load(file)
#dictionary = ast.literal_eval(contents)
d = json.loads(contents)
d.objectfunction()

不过，我无法将 json 字典恢复到对象中。这是我当前状态的代码：

from bitcoinlib.wallets import Wallet #package that I'm using for the "Wallet" object
temp = []
fixedstring = ("id9126923222i09712")
try:
  temp.append(Wallet.create(fixedstring))
  for i in temp:
    with open("backup.json", "wb+") as fp:
      listing = list(fp)
      if temp not in listing:
        dump(temp[0].as_json(), fp, fmt='json')
      else:
        pass
except:
  pass
file = open("backup.json", "r")
contents = json.load(file)
d = json.loads(contents)

file.close()

print(d)

D的输出如下：

因此，我基本上需要将生成的对象转换为 json dict（完成，如​​上所示），然后将其恢复为原始对象形式以再次调用它。我该怎么做呢？
