Classes  Serve as instance factories. If classes are cookie-cutter.

Instances If classes are cookie cutter, Instances are cookies.

class C2: ... # Make class objects (ovals)

class C3: ...

class C1(C2, C3): ... # Linked to superclasses

I1 = C1() # Make instance objects (rectangles)

I2 = C1() # Linked to their classes

classes are really just packages of functions

classes support code reuse and customization of software
