Python version

The default Python version in RR9 applications is Python 3.9.

rrPythonconsole uses 3.9 as well.

RRs python modules are available for Python 2.7, 3.7 and 3.9.

Please use the module SDK\External\Python\rr_python_utils to load the modules.

See our example scripts how to use the utils module.

It chooses the right version for your Python version and caches the modules onto your local machine.
Otherwise network issues can crash your script and RR updates are not possible as long as your script is running.
