def __init__(self, name, age):
    """ Initialize name and age attributes."""
    self.name = name
    self.age = age
def sit(self):
    """ Simulates a dog sitting in response to a command."""
    print(f"{self.name}.title() " + "is now sitting.")
def roll_over(self):
    """ Simulates a dog rolling over in response to a command."""
    print(f"{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.")

This code is not indent properly, does it look that way in your IDE? — Guy, Aug 21 '19 at 11:51
Yes, this is exactly how it looks in my IDE, but I can't figure out where the indentation went wrong. — Samuel Antwi, Aug 21 '19 at 12:18

It is simple- you have not indented anything after class Dog(). Indent it, and everything should be fine.

class Dog():
    """ A simple attempt to describe a dog"""
    def __init__(self, name, age):
        """ Initialize name and age attributes."""
        self.name = name
        self.age = age
    def sit(self):
        """ Simulates a dog sitting in response to a command."""
        print(f"{self.name}.title() " + "is now sitting.")
    def roll_over(self):
        """ Simulates a dog rolling over in response to a command."""
        print(f"{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.")

In python indentation is important,

class Dog():, my_dog = Dog('willie', 6) This code lack in indentation,There are online indentation checker in case you find diffculty.

Please can you provide me any useful site for indentation checker. I am using Visual studio code and the indentation is giving me headache. Thank you very much. – Samuel Antwi Aug 21 '19 at 12:14
