I think so, though I don't really speak perl. The closest approximation is the string formatting operation and the string.Template class. http://docs.python.org/lib/typesseq-strings.html http://docs.python.org/lib/node109.html Kent > > Thanks in advance. > > Python Newbie... > > > On Wednesday 05 October 2005 05:20 pm, Kent Johnson wrote: > >>Eric Walker wrote: >> >>>Well, >>>I think I probably can do this easier in perl but I took a vow I would >>>try and learn python.
