Hello,

I spent an interesting day trying to find out why I could not use the wsdl file with SOAPpy (or with ZSI) then tried to
use SOAPpy calling using home-grown class definitions, but could not get that to work either - because SF.com
rejected the nesting of tags thrown up by SOAPpy - which I could not figure out how to turn-off.

In the end I wrote the following example code for doing it all by hand. If you are really stuck and need to develop in Python this may help you out:

Note I am not offering to support it, if someone would like to make it "safer", "tidier" and extend the data types
please post it back.

Best of Luck
Gareth

PS if you got SOAPpy or ZSI to work let me know how, as that would be neater.
