Update of /cvsroot/python/python/dist/src/Doc/lib
In directory usw-pr-cvs1:/tmp/cvs-serv19160/lib
Modified Files:
	libweakref.tex 
Log Message:
Fix some of the example code; the reference objects do not support a
get() method; just calling them is sufficient. (There was a get() method
for this in an early version of the implementation.)

 Testing that a weak reference object is still live should be done
! using the expression \code{\var{ref}.get() is not None}. Normally,
 application code that needs to use a reference object should follow
 this pattern:

 \begin{verbatim}
! o = ref.get()
 if o is None:
 # referent has been garbage collected
