How to add attributes to existing items

The /give and /replaceitem commands are fine if I want to create a new item with a custom attribute, but is there a command to add an attribute to an existing item?

The closest I've gotten to this is adding attributes to an entity representing a dropped item, but the attributes do not carry over to the item once picked up:

/entitydata @e[type=Item,r=1] {AttributeModifiers:[{...}]}

Thanks in advance!

/data merge entity @e[type=item,distance=..5,limit=1] {Item:{tag:{AttributeModifiers:[{<attribute stuff>}]}}}

Use setattr() to add attributes to a class at runtime

class ObjectClass():

def __init__(self):

self. attribute1 = "attribute1"

def newAttr(self, attr):

setattr(self, attr, attr)

objectClass = ObjectClass()

print(objectClass. attribute1)

setattr(objectClass, "newAttribute", "new attr")
