Time

As another example of a programmer-defined type, we'll define a class called Time that records the time of day. The class definition looks like this:

class Time:
    """Represents the time of day.
    attributes: hour, minute, second
    """

We can create a new Time object and assign attributes for hours, minutes, and seconds:

time = Time()
time.hour = 11
time.minute = 59
time.second = 30

Instead of assigning attributes outside the class, let's define a set method, which takes three integers and assigns them to hour, minute and second attributes:

class Time:
    """Represents the time of day.
    attributes: hour, minute, second
    """

    def set(self, hour, minute, second):
        self.hour = hour
        self.minute = minute
        self.second = second

Let's create a Time instance and set its attributes:

>>> t = Time()
>>> t.set(11, 59, 0)
>>> t.hour, t.minute, t.second
(11, 59, 0)
