New to python and not understanding how imports work. I saw something about how you can do a sys.path.append but I don't want to do this because this needs to go into source control and run off multiple different computers with different pathing. How do I simply import a file that is in another folder but within the same project?

My file structure is 

```
- Project

  - FolderA
    - FileA.py

  - FolderB
    - SubfolderB
      - FileB.py

```

How do I import FileA.py while inside FileB.py?

This doesn't work because I get back 'No Module named FolderA':

```
from FolderA import FileA

class FileB():
...  

```
