Convert fraction of hour to hh:mm:ss

Question

My hourly data set is stored in the time = [0 variable. , 0.08333333, 0.16666667, 0.25, 0.333333, 0.41666667, 0.5 , 0.58333333, 0.666667, 0.75, 0.83333333, 0.91666667, 1. , 08333333, 1.16666667]

Can anyone tell me if there is a simple way to convert this into hh:mm:ss format?

I tried to create a function, but this giving error:

import datetime as dt
from datetime import timedelta

def time2dt(time):

    seconds = int(time*60*60)
    minutes, seconds = int(divmod(seconds, 60))
    hours, minutes = int(divmod(minutes, 60))
    return dt.datetime(hours, minutes, seconds) + dt.timedelta(time % 1)

    dates   = [time2dt(time[i]) for i in np.arange(len(time))]
    datestr = [i.strftime('%H:%M:%S') for i in dates]

Typeerror: int() argument must be a string or a number, not 'tuple'

This error is happening because the divmod that you are calling does not return a number - to have a split rest in Python, simply use the operator % . Divmod returns the entire part and the rest of the division - but that’s not why all the other functions (the "int" in particular) will be able to work automatically with a sequence.

Do the program in parts, without waiting for the language to be "magic" (because it’s not, it’s very rational), and you’ll get the expected result - later on, as you have more resourcefulness, you can worry about wanting to shorten the lines of code:

minutes = time // 60
seconds = time % 60

instead of the incorrect minutes, seconds = int(divmod(time, 60)) that you have there.

(the // is the "integer" split operator that truncates the result).

Also, another problem that you have more down is trying to create a datetime.datetime by spending only hours, minutes and seconds: datetimes need the day, month and year. - create an object datetime.time with day, month and year, and then yes, combine as you wish with other objects.

And finally, not directly related to your problem - but you shouldn’t be using Python 2.7 anymore - in less than two years this version will be completely without support of any kind - it’s been almost 10 years since it was released. 3.x versions of python are current and have various facilities and new features.
