(python) Using Modulo To Get The Remainder From Changing Secs, To Hrs And Minutes

I'm currently new to learning python and stumbled upon this problem: Exercise 2-7 Get the Time Write an algorithm that reads the amount of time in seconds and then displays the

Solution 1:

This is just "out of my head", because I got no testing system I could use right now.

def amount_time(t):
    print("Number of Seconds:", t % 60)
    print("Number of Minutes:", (t // 60) % 60)print("Number of Hours:", (t // 3600))

What "t % 60" does:

1. take t, divide it by 60
2. remove everthing left of the dot
3. multiply with 60

With numbers:

1. 5000 / 60 = 83.33333
2. => 0.33333
3. 0.33333 * 60 = 20

Solution 2:

Your calculation of minuts doesnt work correct, you use Modulo with the hours. You could do the same with minutes as you did wirh seconds instead:

m =     (t - h * 3600) // 60s = int (t - h*3600 - m*60)
ms = int ((t - h*3600 - m*60 - s) * 1000) # milliseconds

and to build the result string there are better ways, f.e.

print'{}:{}:{}.{}'.format(h,m,s,ms)

You find more ways and options to Format, if you look here:
