从父文件夹导入模块 [英] Importing modules from parent folder

问题描述

我正在运行Python 2.5.

I am running Python 2.5.

这是我的文件夹树:

ptdraft/
  nib.py
  simulations/
    life/
      life.py

(我在每个文件夹中也都有__init__.py，为便于阅读，在此省略)

(I also have __init__.py in each folder, omitted here for readability)

如何从life模块内部导入nib模块?我希望无需修补sys.path就可以做到.

How do I import the nib module from inside the life module? I am hoping it is possible to do without tinkering with sys.path.

注意:正在运行的主模块在ptdraft文件夹中.

Note: The main module being run is in the ptdraft folder.

推荐答案

问题似乎与该模块位于父目录或类似内容无关.

It seems that the problem is not related to the module being in a parent directory or anything like that.

您需要将包含ptdraft的目录添加到PYTHONPATH

You need to add the directory that contains ptdraft to PYTHONPATH

您说import nib与您一起工作，这可能意味着您已将ptdraft本身(而不是其父项)添加到PYTHONPATH中.

You said that import nib worked with you, that probably means that you added ptdraft itself (not its parent) to PYTHONPATH.
