RE: [Zope] Another Python Script Question

5 Dec 2003

      Well its getting closer.

If I use this

For object in context.myscript
  Try:
     Context.myscript2
  Except:
    Try:
       Print error
    except NameError, e:
         print e
return e

I catch the 'print error' error (because it is not defined) NOT the
original try error.

If I use 

for object in context.myscript:
   try:
      context.myscript2
   except NameError, e:
         print e
return printed

it does not catch the error at all and brings up the default zope error
message.

If I use

for object in context.myscript:
   try:
      context.myscript2
   except:
         print 'an error has happoned'
return printed

I get the behaviour I want but without the error description :)

Thank you all for your help so far.

Look in a Python manual :-)

The try statement is as follows:

try:
   something
except <exception type>, <var to hold exception info>:
   exception handling code

E.G.:

try:
   print error
except NameError, e:
   print e

Which will print the error you just got...

Unfortunately, except without an exception type doesn't
let you get info on the exception.  This isn't really too
bad because you should use "naked excepts" VERY rarely --
usually at the top level of a UI, because they are likely
to catch things you really didn't want to catch.  You should
usually understand what the expected exception types are
and catch them explicitly.

Yes it works.... sort of
I now get this error
Error Type: NameError
Error Value: global name 'error' is not defined
So I guess error is not the right object to use??

for item in object:
  try:
      context.somescript()
  except:
      print error
return printed

How would I go about using a statement like 'on-error' in a python
script?
Eg.
For item in object:
            context.somescript
            on-error:
                        print error
                        skip
return printed
Thanks
