一个典型模块的内部结构：
样例代码：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
#!/usr/bin/env python #coding:utf-8 "this is a test module" import sys import os debug = True class FooClass(object): "Foo class" pass def test(): "test function" foo = FooClass() if debug: print 'ram test()' if __name__ == '__main__': test() |
|
1 2 3 4 5 6 7 8 9 |
#!/usr/bin/env python #coding:utf-8 def helloworld(): "Hello World! \ \nWelcome to my blog." print 'Nice to meet you!' if __name__ == '__main__': helloworld() |
第一次写与API有关的东西，算是一边练习Python及GAE，一边练习API接口的相关的操作。这是我做的一个利用GAE同步更新饭否与 TWITTER的DEMO，不保存帐户信息，每次需要手工填入用户名密码，再加入数据库存储等相应辅助模块即可做出与HelloTxt、Ping.fm类似的应用。
