I am working on another problem from "How To Think
Like A Computer Scientist". Here is a function:
def increment(time, seconds):
time.seconds = time.seconds + seconds
while time.seconds >= 60:
time.seconds = time.seconds - 60
time.minutes = time.minutes + 1
while time.minutes >= 60:
time.minutes = time.minutes - 60
time.hours = time.hours + 1
Here is the function in action:
>>> from time import *
>>> atime = Time()
>>> atime.hours = 1
>>> atime.minutes = 60
>>> atime.seconds = 120
>>> printTime(atime)
1:60:120
>>> increment(atime,1)
>>> printTime(atime)
2:2:1
Now the exercise is:
As an exercise, rewrite this function so that it
doesn't contain any loops.
I have been staring at this function and drawing a
blank. Something tells me that I need to use
iteration, but I am not sure how I could implement it.
