首先，在要从中导入文件的文件夹中创建一个__init__.py。
The example code below demonstrates how to use path.parent() to get the parent directory of a path in Python:from pathlib import Path path1 = Path(r"C:\folder\subfolder\myfile.txt") path2 = Path(r"C:\Myfile.txt") print(path1.parent) print(path2.parent) Output:...
Use --include-plugin-directory only if you make __import__() calls that Nuitka cannot predict, and that come from a directory, for everything from your Python installation, use --include-module or --include-package. Note The resulting filename will be program.exe on Windows, program.bin ...
