I have the following construction with a long list of around 100 if .. elif. Is there a way do handle this more elegantly in python?

   if isinstance(scen_dep, Class1):
        scen_deps[someEnum.class2].append('1')
   elif isinstance(scen_dep, Class2):
        scen_deps[someEnum.class2].append('1')
   elif isinstance(scen_dep, Class3):
        scen_deps[someEnum.class3].append('1')

Have you considered using a dictionary or similar way of mapping? – Chris_Rands Nov 03 '17 at 15:28

Seems like there should be a method on the specific classes that returns the relevant value. – Daniel Roseman Nov 03 '17 at 15:29
