v = [ v for v in values if v is not None ]
if not v:
return DataFrame()
|
OK -- I'd then need to extract the first item from the list below that. That still preferable? |

@nickeubank hmm, maybe leave it the original (and put in a try except for StopIteration like you did). |
|
whats new is now available for 0.16.1 5ebf521 |
|
pls add a test and a mention in v0.16.1 whatsnew. |

use backticks around groupby.apply and reprase as bit: "would raise if the return value of the user passed function was None "
