帶參數報錯，不帶參數就正常
寫了下老師課堂上的代碼，運行起來老是報錯，發(fā)現只要帶了參數就報錯。這是為什么？
class?Programer(object):
????def?__new__(cls,?*args,?**kwargs):
????????print?("new",?cls)
????????print(args)
????????return?super(Programer,cls).__new__(cls,?*args,?**kwargs)
????def?__init__(self,name?=?None,age=?None?,language=?None):
????????self.name?=?name
????????self.age?=?age
????????self.language?=?language
if?__name__?==?'__main__':
????programer_unerror?=?Programer()
????print(programer_unerror.__dict__)
????programer_error?=?Programer('Alex')
????print(programer_error.__dict__)

我在python2.7上正常，python3.5出現了以上的問題。
如何修復:
return?super(Programer,cls).__new__(cls,?*args,?**kwargs)
修改為：
return?super(Programer,cls).__new__(cls）
這里講的很清楚：
