String Formatting Note When you write:

print("Hello, my name is self.name and I am self.age years old")

The output is literal: Hello, my name is self.name and I am self.age years old.

To output the values of self.name and self.age, you must use string formatting. For example, use an f-string (Python 3.6+):

print(f"Hello, my name is {self.name} and I am {self.age} years old")

Or use the .format() method:

print("Hello, my name is {} and I am {} years old".format(self.name, self.age))
