Python 反射作用

反射 代码示例：
person.py
def run (a):
    print 'running %s'%a
def eat():
    print 'eating'
def talk():
    print 'taliking'

player.py

import  person
def play(action):
    return getattr(person,action)
action =play('run')
action('test')
action = play('eat')
action()

模块反射代码调用示例：
http_download.py

def download(a):
    print 'http download %s'%a
def download2():
    print 'https download 2'
https_download.py

def download(a):
    print 'http download %s'%a
def download2():
    print 'https download 2'

fanshe.py

import http_download
import https_download

def freeman_download(protocol):
    download = __import__(protocol+"_download")
    download.download('test')
    #download.download2()

freeman_download('http')
freeman_download('https')
