Python类装饰器TypeError错误，pythontypeerror,a = Question

a = Question()
a.all_answer() 正常，结果打印到屏幕
但是我想 a.all_answer(write=True) 执行 if write == True:把结果写入文件

但 a.all_answer(True)报错：

TypeError: internal() takes exactly 1 argument (2 given)

a.all_answer(erite=True)也报错：
TypeError: internal() got multiple values for keyword argument 'write'

把装饰函数放到类中也一样。

def write_answer(pre=''):    def wrapper(F):        def internal(write):             if write == True:                 result = F(write)                 with open('/path/a.txt', 'w') as f:                    f.write(result)             else:                 print pre                 F(write)        return internal    return wrapperclass Question(object):    @write_answer('logging...')    def all_answer(self, write=False):        #下面代码部分直接忽略吧        answer_number = self.answer_number()        reg_img = r'http://pic3.zhimg.com/\w+\.jpg'        if answer_number == 0:            print "This question is no answers"        else:            re_br = re.compile(r'<br/?>')            re_allmark = re.compile(r'<[^>]+>',re.S)            all_answer_list = self.soup.find_all( 'div', 'zm-item-answer ')             for each in all_answer_list:                print each.h3.get_text()                  content = str(each.find('div', ' zm-editable-content clearfix'))                 br2n = re.sub(re_br, '\n', content)                for s in br2n.split('\n'):                    print re.sub(re_allmark, '', s)

def write_answer(pre=''):    def wrapper(F):        def internal(self, write):            pass
