Thanks for the suggestion. Very impressed with responses from this
group. I turned your suggestion into a simple class which may be
helpful to others.
title = 'Arbitrary Class'
import string
class ArbitraryClass:
def getClass(self, moduleName):
return __import__(
moduleName,
{},
{},
[]
)
######################################################################
# Run from command line
if __name__ == '__main__':
arbitrary = ArbitraryClass()
#point to any arbitrary class name
target = "any_class"
#instantiate class
instance = getattr( arbitrary.getClass( target ), target)()
#call any_method in any_class
instance.any_method()
sys.exit()
