The easiest way to proceed is simply to call the .py files by different 
names - then they automatically get theor own sys.modules entry.

[sys.modules is a dictionary where you can look modules up by name. it's 
helpful to ensure each module gets its own entry, and the presence of 
the entry is how the system avoids unnecessary reloading of modules].
