Python does not have a case statement. You can use an if-else ladder instead, or use a dictionary with function objects as the values. The dictionary technique is often done like this : def handler1() : print "block 1" def handler2() : print "block 2" def handler3() : print "block 3" switch = { 'a' : handler1 , 'b' : handler2 , 'c' : handler3 } choice = raw_input( "Choose a, b, or c " ) if not switch.has_key( choice ) : print "invalid choice" else : # this is the switch/case statement here switch[choice]() I don't know if that fits in to your framework at all or not. I'm still quite inexperienced at web app design and development, though I've done a fair amount of python and java programming. HTH, -D -- I tell you the truth, everyone who sins is a slave to sin. Now a slave has no permanent place in the family, but a son belongs to it forever. So if the Son sets you free, you will be free indeed.

I'm (slowly) learning Zope, and loving every bit of it, but have run into a few snags. I'm quite comfortable with PHP, which I know is the source of a lot of my problems as Zope and PHP are two entirely different paradigms.

There's just so much information on the Zope website, that I'm having a difficult time finding the answers to certain problems, which unfortunately have left me in somewhat of a quagmire.

Can someone point me to the location where I might find more information on the following, with regards to Zope:

- Variable Passing through GET request

Here's what I'm trying to do: I'm trying to create a "tool-tip" (which is actually contained in a frame) and would like to pass a parameter to the DTML document which contains the HTML, etc. for the tool-tip. Something like: <a href="show_tip?a=b&c=d"> Q: Is there a magical Zope variable that contains the arguments passed on a GET URI (as in PHP?) Q: Must any variable be declared first?

the object is usually called request ( or REQUEST ), ZPublisher marshals them for you http://www.zope.org/Members/Zen/howto/FormVariableTypes

- "case" statement Q: Does there exist the equivalent of a shell "case" statement in Zope? (This is in line with my previous questions).
