Break down your details:
Pkg : falcondup
Module: falconpeer
Class : FalconPeer
Import using the module name:
import falcondup.falconpeer
Create an object using the full path till the class name:
obj = falcondup.falconpeer.FalconPeer()
Once you created the obj, you can call all the method inside the class.
Calling method inside class:
obj.method_name()
And if you want to access class attribute, by using the class name.
falcondup.falconpeer.LogLevel.Info
falcondup.falconpeer.LogLevel.Warn
falcondup.falconpeer.LogLevel.Error
If you want to use inside : class_name.class_var_name
Another scenerio:
if you LogLevel class are in different file which mean different modules, then you need to import that module than you can access it.
