[英]Python imports within a directory
I have a project that is structured thus:我有一个结构如下的项目:
.
|-dir
| |-subdir
| | |-subsubdir1
| | |-subsubdir2
| | |-subsubdir3
| | |-sub_sub_main.py
| | |-other_relevant.py
| |-sub_main1.py
|-dir2
| |-sub_main2.py
|-main.py
Sometimes I need to import functions from other_relevant.py
in main.py
, sub_main1.py
, sub_main2.py
, and sub_sub_main.py
.有时我需要从other_relevant.py
中的main.py
、 sub_main1.py
、 sub_main2.py
和sub_sub_main.py
导入函数。 However, importing the script from different levels of the directory tree causes for the necessary import structure to change.但是,从目录树的不同级别导入脚本会导致必要的导入结构发生变化。
The code in other_relevant.py
and sub_sub_main.py
relies on code in other python files in subsubdir1
, subsubdir2
, and subsubdir3
. other_relevant.py
和sub_sub_main.py
中的代码依赖于subsubdir1
、 subsubdir2
和subsubdir3
中其他 python 文件中的代码。 When I change where I import those two files the import statements in all the python files in those subdirectories have to be changed.当我更改导入这两个文件的位置时,必须更改这些子目录中所有 python 文件中的导入语句。
If I run main.py
or sub_main2.py
which imports other_relevant.py
, it requires the import in other_relevant.py
to use from dir.subdir1.subsubdir1.file import...
.如果我运行导入other_relevant.py
的main.py
或sub_main2.py
,则需要导入other_relevant.py
才能使用from dir.subdir1.subsubdir1.file import...
。
If I am running the sub_main.py
script then the import statement becomes from subdir.subsubdir1.file import...
如果我正在运行sub_main.py
脚本,那么导入语句将变为from subdir.subsubdir1.file import...
If I run sub_sub_main.py
then the import statement becomes from subsubdir1.file import...
.如果我运行sub_sub_main.py
则导入语句变为from subsubdir1.file import...
。
Since the file structure makes sense in terms of how to organize the files I don't want to really change that.由于文件结构在如何组织文件方面很有意义,所以我不想真正改变它。 Is there a way to manage the import statements so that I don't have to change all the import statements in the files in subdir
depending on where I run sub_sub_main.py
and other_relevant.py
?有没有办法管理导入语句,这样我就不必根据运行sub_sub_main.py
和other_relevant.py
的位置更改subdir
中文件中的所有导入语句?
Set the env variable PYTHONPATH
to your top folder path.将环境变量PYTHONPATH
设置为您的顶级文件夹路径。 Then all import statement will be made relative to this folder wherever you execute a python script.然后,无论您在哪里执行 python 脚本,所有导入语句都将相对于此文件夹进行。 For instance from sub_main2.py
you can do:例如从sub_main2.py
你可以这样做:
from dir.subdir.subdir3 import *
Setting up the env variable can be done by sourcing a sourceme.sh file located at the folder path.可以通过获取位于文件夹路径中的 sourceme.sh 文件来设置环境变量。 or directly in the.bashrc if only one project is used.如果只使用一个项目,则直接在.bashrc 中。
sample sourceme.sh:示例sourceme.sh:
export PYTHONPATH=`pwd -P`
