This is because when you issue "import Step" you're actually importing
the "Step" _module_, not the "Step" class inside the module.

You can do this in at least two ways:

------
import Step
a = Step.Step("magn") # access the Step class inside Step module
------

or

------
from Step import Step # insert in the current namespace the Step class
a = Step("magn")
------
