How to run python script with multiple files from console?

Question

I want to run a python script in Blender via the console, but I split the script into multiple files. The folder consists of two files, "main.py" and "poser.py". I call the main script like this:

blender -b --python E:\Development\Python\BlenderPoser\main.py

But I get the following error when trying to import the "poser.py" file:

Error: Python: Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "E:\Development\Python\BlenderPoser\main.py", line 5, in <module>
    from . import poser
ImportError: attempted relative import with no known parent package

What I get from this is that Blender only imports the main.py file, and ignores all of the rest. How can I tell Blender to also import the rest of the files?

Answer 1

I solved it by adding the additional files into a separate folder and adding that folder to the system path:

# Add the folder to the system path, so it can be loaded by the script
main_dir = pathlib.Path(os.path.dirname(__file__)).resolve()
core_dir = os.path.join(main_dir, "core")
sys.path.append(str(core_dir))

After this, I am able to import the poser.py file with import poser
