Hi,thanks for ur reply. My problem is, my code is like #code code code if REQUEST['usr_msg']: do some operations.#some code related to projectmy program control loops with above " if condition". REQUEST is in same context.so once REQUEST stores 'usr_msg ' every time when it goes to "if condition " , it performs that "do some operations"Due to above reason i want to delete that "usr_msg" variable from REQUEST
But if you would really manage to delete this from REQUEST, you would get an exception when trying to use it in the way above. So, see Peters solution to your problem.
also i cannot put restriction on "usr_msg" ,because it comes from user input, and user can give any text to that variable.
If thats some kind of filter chain you probably want to change it to some private name space within request as you would be comfortably getting by REQUEST.set('allmystuff',dict()) at the very beginning. You can actually look up form values from REQUEST.form to distinguish between user input and data from your program. If you just ask REQUEST, you get some kind of stacking layers of name spaces where values get looked up. Please see the Zope book (online) for description of the API. Regards Tino

I want to delete a variable and it value from REQUEST.I used python pop() and __delattr__() ,but getting attribute error. Actually you can't. (Not without writing a product in filesystem and getting deep into zope). Why would you? What you could do is to update one of the requests namespace to give the variable a new value.
