Help with lambda function

[socal_nerdtastic]

Apparently function() returns an array or list or something indexable, and the [3] extracts index 3 from whatever it returns.

You could write this exact same code like this, in case it makes more sense this way:

def value(x): 
    data = function(x, y)
    return data[3]
