Pycharm: Marking a folder as 'sources root'

问题:

I've followed pycharm documentation to set up the IDE to resolve imports. However it seems that each folder containing *.py files needs to be explicitly added as 'sources root' in order for the IDE to resolve all references. Can this be done recursively from a root folder?

Is this the correct way to get the IDE to resolve all codebase references, or have I not set up my project structure correctly?

I have already followed other methods for resolving references in the IDE here and here but to no avail. It seems that the IDE will only resolve them if I manually add each folder as a 'sources root'. Without the recursive functionality, large codebases will be laborious when setting up the IDE!

If you have not used __init__.py, you should add it in each sub-directory to mark it as a package. By adding it, Python will treat the directories as containing packages making you modules visible to other directories and therefore able to be imported.
