"env": {"PYTHONPATH":"${workspaceRoot}"} import包 import的三种方式: 1.绝对import文件 import file # 需要file在执行目录 from dir import file # 需要file在相对于执行目录的./dir/file位置 对于运行入口文件,使用绝对导入。对于非入口文件,使用相对导入。 2.相对import文件 from . import file # 对于非...
The short version is that there is a big difference between directly running a Python file, and importing that file from somewhere else. Just knowing what directory a file is in does not determine what package Python thinks it is in. That depends, additionally, on how you load the file ...
