主要问题:如何从其他目录导入多个Python模块

我已经重新组装了一个项目的存储库，以便根据任务的类型将特定任务的模块放在单个文件夹中，而不仅仅是一个大文件夹.因为我的模块都在一个文件夹中，所以我过去常常能够以这种方式轻松导入:

I've reassembled the repository for a project so that modules for specific tasks are within individual folders according to type of task instead of just one huge folder. Because my modules were all in one folder, I used to be able to import easily in this fashion:

import sys
sys.path.insert(0,'/home/myname/folder_name/all_modules')

现在，我有四个模块文件夹.

Now, I have four module folders.

1. aws_boto_modules
2. 电子邮件模块
3. gen_modules
4. mongo_modules

我想将其中两个模块导入 script_to_run.py .

I want to import two of these modules into script_to_run.py.

我尝试过的不起作用:

import sys
sys.path.insert(0,'/home/myname/folder_name/email_modules')
sys.path.insert(0,'/home/myname/folder_name/gen_modules')

• 我也尝试了sys.path.append.
• 我在本地计算机(MAC OS)上添加了我的PYTHONPATH，一切正常.但是，当我在AWS EC2上更改PYTHONPATH并尝试运行script_to_run.py时，它找不到email_modules或gen_modules.

在过去的三个小时中，我读了很多书，但对于如何进行仍然很困惑.任何指导，包括我可能还没有遇到过的有用链接，将不胜感激.谢谢！

I've read a lot in the last three hours, but am still very confused about how to proceed. Any guidance, including useful links that I may not have encountered already, would be greatly appreciated. Thanks!

推荐答案

__init__.py文件是使Python将目录视为包含包的必需文件.在下图中，我们正在从second_folder导入customer_info模块:

__init__.py files are required to make Python treat the directories as containing packages. In the image below we are importing customer_info module from second_folder:
