[Tutor] Trying to understand sys.getrefcount()

[Tony Cappellini]

I'm using Python 2.3.4

After reading this in the docs
 *getrefcount*( object) Return the reference count of the object. The count
returned is generally one higher than you might expect, because it includes
the (temporary) reference as an argument to getrefcount().I decided to try
some experiments

 class junk(object):
...     pass
...
>>> sys.getrefcount(junk)
5
>>> j1=junk()
>>> sys.getrefcount(junk)
6

sys.getrefcount(j1)
2

I understand why j1 is 1 higher than I expect, based on the docs, but why
does getrefcount(junk) return 5 before any instances of class junk are made?
