我正在尝试使用datefinder.find_dates从txt文件中提取日期,该日期返回生成器对象。在出现以下错误之前,一切正常,直到我尝试将生成器转换为列表。
我一直在寻找解决方案,但是我无法找到解决方案,不确定我也不能真正理解问题。

files = glob.glob(path)
dates_dict = {}
for name in files:
with open(name, encoding='utf8') as f:
dates_dict[name] = list(datefinder.find_dates(f.read()))
返回:

OverflowError: Python int too large to convert to C long
有人可以清楚地解释吗?
预先感谢
重新编辑:在考虑了所做的评论之后,我找到了一个最小的,可读的和可验证的示例。错误发生在:
import datefinder
generator = datefinder.find_dates("466990103060049")
for s in generator:
pass
答案 0 :(得分:1)
这似乎是您正在使用的库中的错误。它试图将字符串解析为一年,但是今年太大了,Python无法处理。 string_agg()
正在使用的库说在这种情况下它会引发一个datefinder
,但是OverflowError
却忽略了这种可能性。
一个快速而肮脏的骇客只是为了使它起作用:
datefinder
