adding 2 1/2 hours to a time object in python
I need to be able to convert time on an time object I recieve from a sql database into python. Here is the current python code I am using without any conversions. I need to add 2 and 1/2 hours to the time.
def getLastReport(self, sql):
self.connectDB()
cursor.execute(sql)开发者_JAVA技巧
lastReport = cursor.fetchall()
date = lastReport[0][0].strftime('%Y-%m-%d %H:%M UTC')
dataset_id = int(lastReport[0][1])
cursor.close()
DATABASE.close()
return date, dataset_id
Have you looked at the datetime module? http://docs.python.org/library/datetime.html
Convert your SQL time into a datetime, and make a timedelta object of 2.5 hours. Then add the two.
from datetime import datetime
dt = datetime.strptime( date, '%Y-%m-%d %H:%M' )
dt_plus_25 = dt + datetime.timedelta( 0, 2*60*60 + 30*60 )
Add datetime.timedelta(0, 2.5*60*60)
.
Try this (switch sqlite3 with whatever db interface you are using):
f= lastReport[0][0]
newtime = sqlite3.Time(f.hour + 2, f.minute + 30, f.second, f.microsecond)
I thought that adding datetime.timedelta(0, 2.5*60*60) like Igancio suggests would be the best solution, but I get:
'unsupported operand type(s) for +: 'datetime.time' and 'datetime.timedelta'.
I usually use the 3rd party module, dateutil, for this sort of thing. It makes this sort of time-shifting much easier to do and understand:
