First Post/ Class Error Question

[buran]

Please, repost your code with proper indentation. Most probably that's the problem, but the code in your post does not produce this error

class Dog(object):
   """A simple attempt to model a dog."""
   def __init__(self, name, age):
       """Initialize name and age attributes."""
       self.name = name
       self.age = age
   def sit(self):
       """Simulate a dog sitting in response to a command."""
       print(self.name.title() + " is now sitting.")
   def roll_over(self):
       """Simulate rolling over in response to acommand."""
       print(self.name.title() + " rolled over!")
my_dog = Dog('willie', 6)
print("My dog's name is " + my_dog.name.title() + ".")
print("My dog is " + str(my_dog.age) + " years old.")

Output:
My dog's name is Willie.
My dog is 6 years old.
