The following does the trick:
from types import MethodType
def addMethod(meth, obj):
f = meth.im_func
setattr(obj, f.__name__, MethodType(f,obj))
def test1():
addMethod(C2.m, C3)
addMethod(C1.v, C3)
o = C3()
o.m()
The same works as is on modifying individual instances, rather than
their class:
def test2():
o = C3()
addMethod(C2.m, o)
addMethod(C1.v, o)
o.m()
# raises AttributeError
# C3().m()
