The inner [DIV(...) for k in data] is a list comprehension.

DIV() doesn't receive a list as parameter, but you must pass a series of 
separate positional parameters (besides the key parameters you can also 
pass). in order for your generated list to be processed correctly, the list 
must be expanded. Hence the * before the [DIV()...]

This is not specific to web2py but normal Python syntax.
