How to round datetime previous 10 minute with python

Question

I want to get the last 10 minutes in python to be fully divisible by 10.

It shouldn't round to the next 10 minutes, it must be always previous 10 minutes.

For example, output should be as follows:

2019-10-04 20:45:34.903000 -> 2019-10-04 20:40

2019-10-04 20:48:35.403000 -> 2019-10-04 20:40

2019-10-04 20:42:21.903000 -> 2019-10-04 20:40

2019-10-04 20:50:21.204000 -> 2019-10-04 20:50

2019-10-04 20:59:49.602100 -> 2019-10-04 20:50

import datetime

def timeround10(dt):
    #...


print timeround10(datetime.datetime.now())

So do you want to modify the datetime object or get a string? Also, have you tried? What do your attempts look like? — Evan, Oct 04 '19 at 17:57

It is not duplicate. The example in the link you gave rounds to the nearest. For example: 10:46 to 10:50 — senjizu, Oct 04 '19 at 18:01

The easiest way is to construct a new datetime with the desired values.

def timeround10(dt):
    return datetime.datetime(dt.year, dt.month, dt.day, dt.hour, (dt.minute // 10) * 10))

def timeround10(dt):
    return dt.replace(second=dt.second // 10, microsecond=0)
