+# Access Instance Variables
+
+You can define instance variables when instantiating a class.
+
+```python
+class Person:
+    def __init__(self, first_name, last_name):
+        self.first_name = first_name
+        self.last_name = last_name
+
+    def full_name(self):
+        return self.first_name + " " + self.last_name
+```
+
+Then those instance variables can be accessed as properties of that class
+instances.
+
+```python
+me = Person("Josh", "Branchaud")
+
+print(me.first_name) #=> "Josh"
+print(me.full_name()) #=> "Josh Branchaud"
+```
