What “is” a List Anyways?
• A list is a special kind of variable
• Regular variables - integer
>>> i = 2
• Contain some data
• Contain some data and capabilities [3, 2, 1]
• Smart variables - string, list
>>> i = i + 1
>>> x = [1, 2, 3]
>>> print x
[1, 2, 3]
>>> x.reverse()
>>> print x
When we combine data + capabilities - we call this an “object”
