Because I do not know the name of the module beforehand (it comes from a database).
'import class2' does not work either, I still need to reload() the module. I discovered also that the instantiation of class2 is persistant between requests when I do not reload the modules. I initialize a list in class1 and then add data from the database to this list. With every request the list grows with the same data from the database so I end up with a load of duplicate data in the list. I have to say that I am quite new to Python, so maybe this persistence is a Python thing...
