Have a look at: http://www.python.org/doc/current/lib/typesseq-strings.html example: for tup in izip_longest(*d, **dict(fillvalue='*')): print "%15s, %15s, %15s" %tup # for a tuple of length 3, you can generalize it > I am struggling to understand how the izip_longest function works > and thus don't really know how it could be manipulated to do the > above. > It would be much apprecited if somoene could also explain how > izip_function > works as I don't like adding code into my programs which I struggle to > understand. > Or perhaps I have to pad out the lists when storing the Strings? > > Any help would be much appreciated. This is an example of "generator" functions, to understand what they are and how they work you can: 1. web-search for "python generators" 2. have a look at "itertools" module, for more generators -- ---- Amit Khemka website: www.onyomo.com wap-site: www.owap.in -- http://mail.python.org/mailman/listinfo/python-list
