This differs from a procedure, which is a set of commands that doesn't necessarily have to return a value. append() Mutates List by adding Element to the end of the list. arguments The inputs to a procedure. (may also be called parameters) attributes Characteristics of an object which may be used to reference other objects or save object state information. name = expression This is an assignment statement. A variable is named and also assigned a value or expression. If multiple values are assigned to the same named variable, the last assignment is the one used. base case An expression that has a value and is not defined in terms of some other thing we are defining. This breaks the chain of recursion. Boolean A value that is either True or False circular definition A definition that doesn't give us answers because it never finishes. It is stuck in a loop with each reference pointing to another reference. It has no base case. class Describes what an object will be, but it isn't the object itself. This is a blueprint for that object. class ClassName (BaseClass): Block How to define a class
