The pyWorkPage contains all the properties (both single value and page mode) associated with the case.  When you want to investigate what the properties are set to as the case moves through the workflow you can open up your clipboard and see all the properties associated with the case on  pyWorkPage. Each case occupies one thread on the clipboard and each thread that has a case contains one pyWorkPage.

Hope this helps,
