python - Converting a float to hh:mm format

Question

I want to print a float value that I've got after performing some math as time string in the hh:mm format. Currently I have the float like 9.888888888888886 and I want it in time like 09:50. I have tried the following code:

    time = str(time)
    time = time.split(".")
    time[1] = float(time[1])
    time[1] *= 0.6
    time[1] = str(time[1])

and when I print I use

    str(time[0]) + ":" + time[1][:2]

Any way to achieve this effect consistently? With more advanced inputs my above code does not work properly, and outputs the wrong time.

Answer 1

Alternatively to using datetime, you can just use simple formatting with a bit of maths, eg:

result = '{0:02.0f}:{1:02.0f}'.format(*divmod(time * 60, 60))

(This assumes that time is nonnegative.)
