Hello, Yongqiang!

os.getcwd() 与 os.curdir 用于获取当前执行 Python 文件的文件夹，直接使用 os.curdir 时会返回 . (表示当前路径)，返回的是当前执行 Python 文件的文件夹，而不是 python 文件所在的文件夹。os.getcwd() 与 os.path.abspath(os.curdir) 返回的结果一样。

以上就是着急冰淇淋为你收集整理的os.curdir - os.getcwd() - os.path.dirname(os.path.abspath(__file__)) os.curdir - os.getcwd() - os.path.dirname(os.path.abspath( file)) 的全部内容，希望文章能够帮你解决os.curdir - os.getcwd() - os.path.dirname(os.path.abspath(__file__)) os.curdir - os.getcwd() - os.path.dirname(os.path.abspath( file)) 所遇到的程序开发问题。
