[Python]从相对路径导入(Importing from a relative path)

keywords: [Python]从相对路径导入(Importing from a relative path)

Case 1

假设python工程结构如下：

Proj/
    Client/
        Client.py
    Server/
        Server.py
    Common/
        __init__.py
        Common.py

要在Client.py中import Common目录。代码如下：

import sys, os
sys.path.append(os.path.join(os.path.dirname(__file__), '..', 'Common'))
import Common

其中os.path.dirname(__file__)表示当前python脚本的所在目录。
