I am glad to be here on active ZOPE mailing list.Let's keep it on the list then; no personal email please.I had initially done the way you have suggested, but it doesn't work in the sense I get a empty list as output, which I know isn't empty.Then something is wrong with the external method. Use a debugger (pdb, Wing, Komodo, etc.) or spurious logging (import logger; logger.getLogger('yourmodule').log) to trace your code.This made me think that I was making silly mistake. If I run external method in python shell it shows the mlist, which is non-empty, but if I ask the same to python script to do what it prints is this :  What do you think is wrong. A further code goes like this: mlist = context.code(uparam) if len(mlist) == str(0): print "Sorry no suitable method found in database" return printed else: print mlist return printedUse "if not len(mlist):"; comparing the length to str(0) is always false. "len" returns an integer, not a string, so 0 == '0' will never be True. You can also call the external method directly if you encode the arguments passed to it in the query string. Just open up a python propmt, import urllib and call urllib.quote on your argument list to hand-construct a URL. Moreover, get decent books on Python and on Web programming in general.

I wonder which books would recommend? Best I can say is that books just about HTTP are probably the least appreciated and often the most useful.
