Hello, everyone! I'm writing a ROS service for my robot in Python. I have one file which contains all code in arm_mover.py . The code has become too big and I need to replace a part to another module helpers.comm. But I don't understand how I must import my new module to the main script. Lines like 'import helpers.comm' or 'import package_name.helpers.comm' don't work.

/package_root
 |--/scripts
 |   |-----arm_mover.py
 |--/src
     |-----/helpers
           |--__init__.py
           |--comm.py

Thanks, for help.

You got that `import roslib; roslib.load_manifest('my_package')` line in your script?

I have found a decision by myself. But it's not so elegant:

path = os.path.dirname(__file__) + "/../src/"
sys.path.append(path)

Maybe someone has a more pretty idea.

You could add imports for the needed classes/... in the __init__.py file, but again that is now a clean way
