Lokad can be accessed programmatically through our web services. We are already providing tutorials for quite a few languages, namely C#, Java, PHP and C++.
But we were not providing any Python tutorials so far, although there are several promising ERP implemented in Python. If you're not convinced, have a look at TinyERP and ERP5.
Thanks to Maxim Krikun, we have now a complete Python tutorial that explains how to use our Forecasting Web Services. As usual, the source code has been released as open source on SourceForge.
