using git submodule in flask

[Kugeleis]

From my main flask app.py I call a function in a file foo.py inside a git submodule. Starting flask fails sind it does not understand the imports there. I tried this workaround adding the git submodule folder to sys.path but didn't succeed.

├── app.py
├── git_submodule/
│ ├── foo.py
│ ├── some_module/

What is the correct way to make the imports in git submodule accessable to flask?

works if sys.path.append is don befoere imports
