You also need MyModule/__init__.py to signal to Python that MymModule is a package. (Actually you 
are creating a package containing several modules.)

In MyModule/__init__.py put
from MyModule.a import classA
from MyModule.b import classB
from MyModule.c import classC

This creates package-level attributes for the classes.

Can you say why you want to do this? It is possible but generally it is better to use a dict:
values = {}
values['x'] = 3
