Reference or value?  Neither one.  This assignment is no different than 
any other attribute assignment in Python.  Technically, it binds the 
name __repr__ to the function object already bound by __str__.  You now 
have a second name pointing to the same object.  Rebinding one of those 
names  to yet another different object won't affect the other name.

name1 = "this is a test"
name2 = name1
name1 = "another string"           #this has no effect on name2

print name1, name2
