The Time Convert challenge is the challenge I am going to explain in this article. The description below is taken straight from the Coderbyte website:

Have the function TimeConvert(

num) take thenumparameter being passed and return the number ofhoursandminutesthe parameter converts to (ie.ifnum= 63 then the output should be 1:3). Separate the number of hours and minutes with a colon.

The first step is to find out the hour from the **num **parameter. The hour can be found by dividing the **num** parameter by 60, which represents the number of minutes in an hour. However, in Python, there is a thing called floor division – the result of the division is rounded to the next smallest whole number, leaving out the remainder. *E.g. 10//4 returns 2, whereas 10/4 returns 2.5*. The line below does just that, it extracts the hour.

hour = num // 60

Once the hour is found, the next logical step is to find the minutes. The minutes are found by using the modulo (%) operator. The modulo operator returns the remainder of the division. *E.g. 63 % 60 returns 3.* Thus, the variable *minutes* from below extracts and stores the number of minutes from the **num** parameter.

minutes = num % 60

The last thing to do is to put the hours and minutes together. That can be done in different ways. In this case, I have decided to use the .format() method. The .format() method is a useful method, so it is worth a read about it here.

time = "{}:{}".format(hour, minutes)

Another alternative to the above code is:

time = str(hour) + ':' + str(minutes)

The challenge is solved. The full solution put together, can be seen below:

def TimeConvert(num): # Floor division - division that results into whole number adjusted to the left in the number line hour = num // 60 # Modulus - remainder of the division of left operand by the right minutes = num % 60 # put the hour and minutes together time = "{}:{}".format(hour, minutes) return (time)
