Question

I am generating objects using type for using some of the code that is previously written

# Assume that myAppObjDict is already initialized.
myAppObj=type("myAppClass", (object,),myAppObjDict)

Now I want to add a method say myValue()in it so that if I should be able to call

value=myAppObj.myValue() 

What should be the approach?

Answer 1

You should add the methods to myAppObjDict before you create the class:

def myValue(self, whatever):
    pass
myAppObjDict['myValue'] = myValue

# Assume that myAppObjDict is already initialized.
myAppObj=type("myAppClass", (object,),myAppObjDict)

Alternatively define a base class containing the methods and include it in your tuple of base classes.

class MyBase(object):
    def myValue(self): return 42

# Assume that myAppObjDict is already initialized.
myAppObj=type("myAppClass", (MyBase,),myAppObjDict)
