dateTimeStart = "2014-01-01 12:00:00"

def main():
    dateTime1 = datetime.strptime(dateTimeStart, "%Y-%m-%d")
    today = date.today()

    if dateTime1 > "today":
        print "No"

if __name__ == "__main__":
  main();

回答1:

You need to parse the time part as well:

datetime.strptime(dateTimeStart, "%Y-%m-%d %H:%M:%S")

Then you can compare your dates like this:

if dateTime1.date() > date.today():
    print "No"

The date() function returns the date of a datetime object.
