I would like to use the following recipe to transpose a list of lists with different lengths. http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/410687
Here is an example of what I would like to do: Python 2.5.1 (r251:54863, May 18 2007, 16:56:43) [GCC 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)] on cygwin Type "help", "copyright", "credits" or "license" for more information. >>> a = [[1,2,3],[4,5,6,7],[8,9]] >>> print map(lambda *row: list(row), *a) [[1, 4, 8], [2, 5, 9], [3, 6, None], [None, 7, None]] >>> However, in the Python 3000 FAQ (http://www.artima.com/weblogs/ viewpost.jsp?thread=211200), Guido says not to use map with lambda because a list comprehension is clearer and faster. How can I rewrite the above recipe using a list comprehension instead? -sofeng -- http://mail.python.org/mailman/listinfo/python-list
