[Python-checkins] CVS: python/dist/src/Doc/lib libweakref.tex,1.10,1.11

[Fred L. Drake]

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.)

Reported by Mats Wichmann.

  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
