当前执行这条import语句的脚本所在的路径 working directory。

影响fopen的文件。 【1】

• img_path = '../deepwater.jpg'。working directory必须是在1下

  learn_python\docs\工程路径\1$ python main.py
  

• img_path = '工程路径/deepwater.jpg'，working directory必须是在docs下

  learn_python\docs$ python 工程路径/1/main.py
  

• img_path = os.path.join(sys.argv[0], '../..', r'deepwater.jpg')根据main.py定位, 所以随便working directory.
• img_path = os.path.join(__file__, '../../../..', r'deepwater.jpg')根据mod2_main.py自身定位, 所以随便working directory.
