我正在修改Python中的OOP，并尝试从另一个子类继承属性，但我不知道如何或是否可能。这是我到目前为止所拥有的：

class Developer(Employee):
  def __init__(self, first, last, pay, prog_lang):
    Employee.__init__(self, first, last, pay)
    self.prog_lang = prog_lang
    self.email = first.lower() + '.' + last.lower() + '@outlook.com'

class BetaTester(Employee, Developer):
  def __init__(self, first, last, pay, prog_lang, platform):
    self.platform = platform    

我收到的错误是：

Traceback (most recent call last):
  File "main.py", line 33, in <module>
    class BetaTester(Employee, Developer):
TypeError: Cannot create …
