Huanggo code to illustrate: Python syntax sugar

Here is an example to illustrate:

#coding: Utf-8

"""

The function of the Foo = decorator (foo) statement is to pass the Foo function as a parameter to the decorator

The return value is assigned to Foo, so Foo is no longer the original function.

To simplify the code, Python adds an adorner to this syntactic sugar

Makes

@decorator

def foo ():

Print ("Welcome to Huanggo Python training")

Print ("Consulting qq:1465376564")

Print ("Https://github.com/pythonpeixun/article/blob/master/index.md")

The same effect as Foo = decorator (foo)

"""

def decorator (func):

def inner ():

Print ("Begin func Call")

Func ()

Print ("After func call")

return inner

def foo ():

Print ("Welcome to Huanggo Python training")

Print ("Consulting qq:1465376564")

Print ("Https://github.com/pythonpeixun/article/blob/master/index.md")

@decorator

Def foo2 ():

Print ("Welcome to Huanggo Python training")

Print ("Consulting qq:1465376564")

Print ("Https://github.com/pythonpeixun/article/blob/master/index.md")

foo = decorator (foo)

Foo ()

Print ("***************************")

Foo2 ()
