RecursiveContinue running functions within the function, knowing that a goal is reached and the final return value.Characteristics of recursion:1. The function must have a definite end condition2. Without entering a recursion, the problem that needs to be addressed should be reduced3. Recursive efficiency is low, need to prevent memory overflowClass Exercises　1.

which such objects are ordered is random but will always be consistent. when any one operand is a complex number, the, =, > , and > = operators throw TypeError exception. Non-identical instances of a class are typically not equal unless the class defines the __eq__ () or __cmp__ () method.An instance of a class cannot typically be sorted with other instances of the same class or other types of objects unless the class defines a sufficiently rich comparison method (__ge__ (),__le__ (),__gt__
