Compile a function. When n is an even number, call the function to calculate 1/2 + 1/4 +... + 1/n. When n is an odd number, call the function 1/1 + 1/3 +... + 1/n ., Even number
First, write a function whose n is an even number:
Def peven (n): s = 0.0 for I in range (2, n + 1.0): s + =/I print 'value:', s
Write another function with n as an odd number:

AOP (Aspect-Oriented Programming): a new methodology that complements traditional OOP (Object-Oriented Programming.
The main programming object of AOP is the aspect (aspect), while the aspect modular cross-cutting concerns.
When applying AOP programming, you still need to define public functions, but you can clearly define whe
