Time is not defined - Class python

Question

I've been trying to make this class called Time with has the attributes of hour,minutes and seconds, that also has accessor functions and mutator functions such as set_hour, increment_hour and so on.

This is my code, I cannot get it to work I get the error Time is not defined or t is not defined when i switch the last lines around. Python 3.2.5 by the way.

class Time:
    """The Time class defines the time with
    attributes: hour, minute, second
    """
    #Attributes
    hour = 12
    minutes = 00
    seconds = 00

    #Functions
    def get_hour(self):
        return self.hour

    def get_minute(self):
        return self.minute

    def get_second(self):
        return self.second

    def print_time(self):
        print("Hello, the current time is", self.hour,":",self.minute,":",self.second)

    def set_hour(self, new_hour):
        self.hour = new_hour

    t.set_hour("1")
    print(t.get_hour())
    print(t.print_time())
    t = Time()

Answer 1

It seems you are invoking the method set_hour("1") on a variable t before that variable has been initialized by t = Time().

EDIT: and correct the indentation as said in the comments. I'm not a Python programmer so I didn't catch that.
