Okay, it appears the method in a class has its own ID, but all
instantiations of that method have identical IDs. But what happens if we
have a huge number of instantiations trying to access the identical method
at the same time?
Um, they all get given access to the method? I'm not sure what you think should
be happening here:
class MyClass:
def setdata(self, data):
self.data = data
def getdata(self):
print(self.data)
MyClass.setdata
<function MyClass.setdata at 0x026CACD8>
id(MyClass.setdata)
40676568
f = MyClass()
g = MyClass()
Two instances of the class.
id(f.setdata)
43576616
id(g.setdata)
43576616
Two references to the same method obtained from the class.
d = MyClass()
id(d.setdata)
43576616
And a third.
Steven D'Aprano posted a decent explaination in your other thread ("Are the
methods in a class copied or just linked to?"); it would have been helpful if
your post had stayed in that thread - it is essentially the same discussion.
So all your "d.setdata" expressions consult various places in order to find the
method definition, and they all find it in the class. And so you are given the
same method every time, and thus the same id.
