del does nothing but remove one binding early.
As far as effect on the underlying object,
del v
and
v = None
have the same effect.

The del in main is superfluous. For all but the last iteration,
the objC = c.cClass() will dereference the previous objC, and
the final trip through the loop ends up by exiting the function
which will have a similar effect.
An experiment which will show this:
import sys
q = r = object()
print sys.getrefcount(q),
del r
print sys.getrefcount(q),
r = q
print sys.getrefcount(q),
r = None
print sys.getrefcount(q)
Note that whenever you call sys.getrefcount, the argument to the
function itself will increase the count by 1. This demonstrates that:
print sys.getrefcount(object())
