Import error on python package inside django project

Question

I am new to python and i have this django project, which actually has to communicate with a python package that my colleague has built. Let's say, the structure is as follows

-Mydjangoproject
      -myapp
         -views.py
         -models.py

      -Mydjangoproject
         -settings.py
         -urls.py

      -manage.py

      -db.sqlite3

      -colleagues_python_package
         -package1
            -script1.py
            -script2.py
         -package2
            -info1.py
            -info2.py

When I try to run my colleague's script1.py which has the following code to import,

from colleagues_python_package.package2 import info1

it throws me the error

ImportError: No Module named colleagues_python_package.package2

If run in my colleague's system, this works. Is it because this package is not set in PYTHONPATH. How do I resolve this and explanation? ( and this package has to be inside django project)

Answer 1

Okay I found that I have to import using [dot] 's. For example, if I want to run the script1 , I'll have to import info1 as below

from ..package2 import info1

Representation is like,

1 dots - current folder 
2 dots - current folder's parent 
3 dots - current folder's parent's parent

Hope I ain't confusing.

Answer 2

尝试从python manage.py shell导入模块，看看是否会出现任何错误。
