I’m getting errors with this function:
def compare_dates(date1: str, date2: str) -> str:
date1_obj = datetime.strptime(date1, "%Y-%m-%dT%H:%M:%S")
date2_obj = datetime.strptime(date2, "%Y-%m-%dT%H:%M:%S")
return date1 if date1_obj > date2_obj else date2
Because the input sometimes includes microseconds. Is there a clearer way of dealing with this than what I’ve done?
def compare_dates(date1: str, date2: str) -> str:
date_format = "%Y-%m-%dT%H:%M:%S"
date1_obj = datetime.strptime(date1.split(".")[0], date_format)
date2_obj = datetime.strptime(date2.split(".")[0], date_format)
date1_obj = date1_obj.replace(microsecond=0)
date2_obj = date2_obj.replace(microsecond=0)
return date1 if date1_obj > date2_obj else date2
You must log in or # to comment.
That looks like ISO8601 format so you can use fromisoformat to make the parsing a bit simpler. I’m not clear why you need to drop the microsecond part. Surely if one timestamp is a few microseconds past the second it is later.
d1 = datetime.fromisoformat(date1) d2 = datetime.fromisoformat(date2) return date1 if d1 > d2 else date2if you are reasonably confident your input dates match your format, you could just
return date1 if date1>date2 else date2and call it a day.Second this : this is a strong benefit of using ISO8601 format as you do : you can use alpha-numeric sort directly.
