Some of the modules in the Python standard library make things a little more difficult than other languages.(Perl, Ruby, ...) This is a good example of it. Are there any 3rd party modules that let you set the expiration date to 'yesterday'? I know I could write a wrapper, but I'd rather not re-invent the wheel and save some time. Another example is ftplib. Other language's ftp modules/libraries allow you do something like sendaciifile(fh) or sendbinaryfile(fh) yet you need to build your own wrapper functions in Python. http://effbot.org/librarybook/ftplib.htm Mike _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
