---------------------------------------
Hey folks,
I do really want to start adding Python UDFs to PiggyBank, but I'm still hazy
on the tests question I asked above. Does anyone have an answer, so I could
start sharing my udfs and hopefully help out?
> Creation of a Python PiggyBank
> ------------------------------

> Key: PIG-2529
> URL: https://issues.apache.org/jira/browse/PIG-2529
> Project: Pig
> Issue Type: New Feature
> Components: piggybank
> Reporter: Eli Finkelshteyn
> Priority: Minor
> Labels: piggybank, python
>
> As per a conversation on the Pig user list, I think it makes sense to create
> a PiggyBank for Python functions. To get us started, here's something short
> and quick I wrote to convert a bag of single item tuples to one single tuple:
> @outputSchema("t:tuple()")
>
> def bagToTuple(bag):
>
> t = tuple([item[0] for item in bag])
>
> return t
