?????????這篇記錄的是python的類以及文件的引用等。

???????? 文件???WORK.py:

???????? 類外函數(shù)，宏等

???????? def B():

????????????? pass

???????

?????????TAET_DATA = 3

???????? class A():

?????????????????

????????????? def __init__(self):

????????????????????self.num = 2

??????????????????? pass

????????????

????????????? def count_data(self):

??????????????????? return self.num

????????

???????? 定義全局變量：

????????

???????? instance = None

???????? def root():

?????????????? global instance

?????????????? if not instance:

????????????????? instance = A()

????????????? return instance

?????????定義一個(gè)主文件? TEST.py

???????? 可在頂部定義編碼類型：

???????? # -*- coding: gbk -*-

?????????或者

?????????# -*- coding:?UTF-8 -*-

????????

???????? import WORK

???????? 或者

???????? from WORK import instance

?????????from WORK import *

?????????from A import A

???????? 若文件在另外一層目錄 ITEM 下

???????? 該目錄下定義一文件 __init__.py

???????? 寫上文件頭即可,如

?????????# -*- coding:?utf-8 -*-

???????? 在TEST.py

???????? from ITEM.WORK import instance

????????

?????????定義主函數(shù)

???????? def main():

???????????? com = WORK.root()

?????????????num = com.count_data()

???????? if __name__ == "__main__":

???????????? main()

????????

???????? 我暈，好像越寫越亂了。。。。

????????

還是pyhton
