 - link = None
 - abstract = None
 - keywords = []
 - content = None
 - pub_date = None
 - xxx = '99999'
 - def __init__(self):
 - for p in dir(self):
 - if not p[0:2] =='__':
 - exec('self.'+p+' = Article.'+p)
 - pass
 - a = Article()
 - print(a.__dict__)
 - output: {'abstract': None, 'content': None, 'keywords': [], 'link': None, 'pub_date': None, 'title': None, 'xxx': '99999'}
