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?
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)
You should be able to assign any function to the class after creation:
def method(self):
print self.__class__.__name__
def my_class (object):
pass
my_class.method = method
o = my_class()
o.method()
You can do this assignment at any time, and all object will have the new method added, event those already created.
After all, Python is a dynamic language :)
