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.

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()
