Convert seconds to minutes and seconds

Question

I've written some code in python 2.7 for a timer program. The downside is that the result is in seconds and I need it in Minutes:Seconds. I've tried to format the time to no avail. Can anyone help?"

from Tkinter import *
import time

root = Tk()
root.title("Timer")
canvas = Canvas(root)
canvas.pack()

time=1

def tick():

    canvas.delete(ALL)
    global time
    time += 10


    if time >= 120:

        canvas.create_text(180,140, font = ("Calibri",200),text=time,fill='red')
    else:

        canvas.create_text(180,140, font = ("Calibri",200),text=time,fill='green')
    if time == 1000:
        time = 0
        tick()
    else:
        canvas.after(1000, tick)

def reset():
    global time
    time = 0

def close_window():
    root.destroy()

b = Button(root,text="Reset", command=reset)
c = Button(root,text="Quit", command=close_window) 
b.pack(side = LEFT)
c.pack(side = RIGHT)
canvas.after(1, tick)
root.mainloop()

Answer 1

You can use datetime.timedelta

import datetime
number_of_seconds = 1000
str(datetime.timedelta(seconds=number_of_seconds))

# output
'0:16:40'

Or even better since you only want mm:ss, you can use time.strftime

import time
number_of_seconds = 1000
time.strftime("%M:%S", time.gmtime(number_of_seconds))

# output
'16:40'

Documentations are available for datetime module and for time module.

Being a somewhat-lazy programmer, I like to reuse good work that's embodied in the standard library (where it might well get optimized and is surely very well tested). So...:

import datetime
def secs_to_MS(secs):
    return datetime.datetime.fromtimestamp(secs).strftime('%M:%S')

If you need to have hours there as well, that's easy too:

import datetime
def secs_to_HMS(secs):
    if secs < 3600:
        return datetime.datetime.fromtimestamp(secs).strftime('%M:%S')
    else:
        return datetime.datetime.fromtimestamp(secs).strftime('%H:%M:%S')
