Google App Engine - Importing my own source modules (multiple files)

Question

I am writing a GAE application and am having some difficulty with the following problem.

I've created multiple python files (say a.py and b.py) which are both stored in the same folder. I am able to call code in a.py or b.py by mapping URL's to them (using app.yaml). What I haven't figured out how to do is import the code from one into another.

Can anyone help me with the syntax and/or any config that is required here? For instance, I am under the impression that I can include the code from b.py in the file a.py by issuing the following statement in a.py

import b

I'm not having any success with this approach. Specifically I receive this error:

ImportError: No module named b

Any suggestions?

Thanks,

Matt

Answer 1

Have you tried importing as if you were starting at the top level? Like

import modules.b

Answer 2

If the files a.py and b.py aren't located, be sure to include the respective paths in sys.path .

import sys
sys.path.append(r"/parent/of/module/b")

Answer 3

请注意，GAE的常用模式不是每个都在app.yaml中独立映射，而是让一个“处理程序”脚本具有映射到它的所有（或除静态和特殊）URL，并具有该脚本导入a和b并使用他们定义的处理程序。

Answer 4

正如@toby所说，它必须像从顶层目录导入一样导入，并且必须将名为init .py的文件放在该文件夹中。
