[ ] defines a list literal >>> [1,2,3] [1, 2, 3] >>> type(_) <type 'list'> This particular syntax [ ____ for ___ in ___] is a list comprehension. It's creating an inline for-loop to generate a list. You can just lift the whole expression for the assignment. result = [ dict(x1 = elem.x1, x2 = elem.x2, x3 = elem.x3,) for elem in method(in_values) ] return result > > -- > http://mail.python.org/mailman/listinfo/python-list > -- http://mail.python.org/mailman/listinfo/python-list
