Parsing a date that can be in several formats in python

Question

I would like to parse a date that can come in several formats, that I know beforehand. If I could not parse, I return nil. In ruby, I do like this:

DATE_FORM         


        

Answer 1

After your tip, RocketDonkey, and the one from Bakuriu, I could write a shorter version. Any problem with it?

def parse_or_none(date):
    for date_format in DATE_FORMATS:
        try:
            return datetime.strptime(date, date_format)
        except ValueError:
            pass
    return None
