you may use [`datefinder`](https://pypi.org/project/datefinder/) — Abhyudai, Nov 15 '19 at 21:31
datefinder is giving way too many dates which are not even there in the text. — Sarfraj Ansari, Nov 15 '19 at 22:00
Are these the only formats which you're looking at ? or there are more such formats ? — Swarnveer, Nov 16 '19 at 02:30

You can put each of your regular expressions into its own capture group, and "or" them:

(regex1)|(regex2)|(regex3)

This will match against any string that satisfies at least one of your regular expressions.
