Make sure, the script you execute by passing it to the python
interpreter is in the parent directory of Sub_Dir.
Additionaly put an empty file called __init__.py (double underscores!)
in Sub_Dir if you don't already have.  This is necessary to use Sub_Dir
as a package and import modules from it.

For more details see:
http://docs.python.org/3.3/tutorial/modules.html#packages

When using "from...import" on the module that contains the class, you
can use the class without the package identifier:
q_api = My_Class_Connector(string1,string2)

For your information: I think beginner questions like this one should be
asked on the tutor list:
