无效的日期时间错误

Question

我正在使用 datefinder 模块在文本中查找日期参考。但是，函数调用返回的生成器可能会返回无效日期。如何使用 try-except 块解决这个问题？

import datefinder
file = open('abc.txt', 'r')    
for text in file:
     dates = datefinder.find_dates(text)

     for one_date in dates:        #Getting an error at this point if date is not in the range
         if valid_date(one_date):
             #some code here

Answer 1

import datefinder
file = open('abc.txt', 'r')    
for text in file:
       dates = datefinder.find_dates(text)
       while True:
                    try:
                        one, flag = self.valid_date((str1.__iter__()).next())
                        if flag:
                            *some code here*
                    except ValueError:
                        continue
                    except StopIteration:
                        break
