[Zope] Another Python Script Question

[Tim Zegir]

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.
