It's not integer vs set; it's the difference between rebinding and
calling a method. It's nothing to do with object orientation; the same
happens with ordinary variables:
>>> a=b=1
>>> a,b
(1, 1)
>>> a=2
>>> a,b
(2, 1)
>>> c=d=[]
>>> c,d
({}, [])
>>> c.append("Test")
>>> c,d
(['Test'], ['Test'])
But:
>>> c=['Foobar']
>>> c,d
(['Foobar'], ['Test'])
When you do a=2 or c=['Foobar'], you're rebinding the name to a new
object. But c.append() changes that object, so it changes it
regardless of which name you look for it by.
