Python JSON 文件格式

Question

您好，我正在尝试创建 JSON 文件，但无法格式化文件。 下面我将提供代码和输出。

代码：

def writeToFile(self):
    self.json_conceivement = os.path.join("./",'NoobPremeNewEggLogIn.json')
    self.accounts = {}
    if os.path.exists(self.json_conceivement):
      try:
          with open(self.json_conceivement) as f:
              self.accounts = dict(json.loads(f.read()))
      except:
          pass
      self.accounts = {}
    else:
      try:
          with open(self.json_conceivement) as f:
              self.accounts = {}
      except:
          pass
      self.accounts['Profiles'] = []
      
  
    self.autoSave()

def autoSave(self):
   with open(self.json_conceivement, "a", encoding='utf-8') as outfile:
       json.dump(dict(self.accounts.items()), outfile,ensure_ascii=False, indent=4)

输出：（如果我运行一次，预计）

{
    "Profiles": []
}

输出：（如果我运行两次，不正确）

{
    "Profiles": []
}{}

想要的输出：

{
    "Profiles": [{}]
}

任何帮助将不胜感激

改变这一行

with open(self.json_conceivement, "a", encoding='utf-8') as outfile:

到

with open(self.json_conceivement, "w", encoding='utf-8') as outfile:
