[Zope] basis Zope/Python script question

[H.de.Wit@SFK.NL]

Hello,

I write the following code repeatedly:

if request.has_key('v1'):
  v1=request.v1
else:
  v1=-1

if request.has_key('v2'):
  v2=request.v2
else:
  v2=-1

etc.

Is there a way to do this more efficient and clean, something like this:

for reqvar in ['v1','v2','v3']:
  if request.haskey(reqvar):
     reqvar=request.reqvar                 #this doesn't work
  else
    reqvar=-1                                          # and this also not.

Het vriendelijke groeten,
